A Sore Throat Lasting More Than 10 Days: Understanding It and Responding Naturally

A quick reminder to start with: a sore throat is an inflammation of the tonsils. These are two tissue glands located on either side at the back of the throat. They are lymph nodes that play a major role in immunity. The tonsils are there to trap bacteria or viruses that might enter our body through the throat. They act as a first line of defence by producing antibodies and activating immune cells. This protective function explains why they are often the first to be affected during respiratory infections. There are two types of sore throats: those caused by viruses and those caused by bacteria.

Viral sore throats account for about 80% of cases in adults and are caused by various viruses such as adenovirus, Epstein-Barr virus, or rhinovirus. Bacterial sore throats, on the other hand, are mainly caused by Group A streptococcus. This distinction is crucial, as it entirely determines the course of treatment.

A sore throat is considered prolonged if it lasts longer than 10 days. That is, it persists despite the initiation of appropriate treatment. This contrasts with a typical sore throat, which improves within a few days and most often does not require antibiotics when viral in origin.

It is worth noting that viral tonsillitis resolves spontaneously within 3 to 5 days, up to 7 days at most. In contrast, bacterial tonsillitis treated with a specific antibiotic shows improvement within 24 to 48 hours after treatment begins and resolves within 5 to 7 days. This improvement is generally marked by a decrease in fever, reduced pain when swallowing, and a gradual return of appetite.

If symptoms persist beyond 10 days, this is outside the norm. This is one of the signs that should prompt you to see your doctor again promptly. This applies whether you have white strep throat or red strep throat that lasts more than 10 days. This unusual duration may mask complications or reveal an underlying cause that requires further investigation.

Several mechanisms can explain this abnormal duration:

Inflammation: it refuses to subside in the tonsils. Normally, after a few days, the inflammatory process gradually subsides. If it persists, it is a sign that an external factor is fueling this inflammation. This chronic inflammation can be fueled by irritants such as tobacco, pollution, acid reflux from the stomach, or allergens present in the environment. The body then continues to produce inflammatory mediators that maintain the symptoms.

The microbiome: The mouth and throat are rich in microorganisms known as oral flora. Typically, good and bad bacteria coexist, which helps maintain good health. However, a prolonged infection can disrupt this balance and lead to an overgrowth of harmful bacteria. This imbalance, known as dysbiosis, can be exacerbated by the use of broad-spectrum antibiotics, which also eliminate the beneficial, protective bacteria. It can then take several weeks for this ecosystem to regain its natural balance.

Good to know: It’s important to distinguish between persistent tonsillitis and recurrent tonsillitis. With recurrent tonsillitis, there is a recovery period between each episode (even if brief). With persistent tonsillitis, symptoms remain present. Recurrent tonsillitis particularly affects children and some adults who experience more than five episodes per year. It sometimes requires different treatment, and in some cases, even tonsil removal (tonsillectomy).

But why won’t the sore throat go away? There are several possible explanations, and it’s important to know them to understand why seeing a doctor is crucial.

Microbial resistance: One of the most common causes is that the streptococcus responsible for your bacterial strep throat is resistant to the antibiotic treatment prescribed. Although this is a relatively rare occurrence, it is becoming increasingly common. This is due to patients frequently self-medicating with antibiotics without medical advice. This resistance can also result from an incorrect choice of initial antibiotic or an insufficient dosage. Certain strains of streptococcus develop defence mechanisms against the most commonly used antibiotics, rendering the treatment ineffective.

A quick reminder: Antibiotic treatment involves a specific molecule and dosage for a defined regimen and a specific condition in a patient at a given time. It is not advisable to shorten the treatment duration on your own, to share your medication with another person in the same situation, or to extend your treatment without medical advice. Prematurely stopping antibiotic treatment is one of the main causes of bacterial resistance.

A secondary infection has set in: It is possible that the sore throat started as a viral infection and that bacteria took advantage of weakened immune defences and a favorable environment to take hold and cause what is known as a secondary infection. Result: you end up with two infections and an initial treatment that is certainly no longer appropriate for your situation. This situation is particularly common in people whose immune system is weakened by stress, fatigue, or other concurrent conditions.

Regular reinfection: If someone in your circle is a carrier of the microbe without being sick, they can reinfect you. This is the case, for example, within the family or in communal settings (office or school). Shared personal items (glasses, cutlery, etc.) can lead to ongoing reinfection. These asymptomatic carriers account for 10 to 15% of the population and can transmit the bacteria without showing symptoms themselves. This is why it is sometimes necessary to treat close contacts in cases of recurrent tonsillitis. This decision may be made by the doctor depending on the situation.

Complications can sometimes develop with tonsillitis. These complications can then lead to other conditions such as:

An abscess: A pocket of pus that forms near the tonsils. This complication often requires surgical drainage and can cause difficulty swallowing or even breathing problems.

A lymph node infection: The lymph nodes become infected. They then become painful and swollen and may be accompanied by a high fever.

Sinusitis or otitis: The infection has spread to the sinuses or the eardrum, thereby spreading the immune system’s inflammatory response. This spread is facilitated by the anatomical proximity of these structures.

A weakened immune system: This occurs during periods of intense stress, chronic fatigue, serious conditions such as diabetes, or when taking treatments that suppress the immune system. This is the case, for example, with certain medications such as cortisone. The elderly, pregnant women, and patients undergoing chemotherapy are particularly at risk.

A consequence of another condition: Sometimes a sore throat is a consequence of another condition, such as infectious mononucleosis (the "kissing disease"), gastroesophageal reflux, which can irritate the throat, or autoimmune disorders. In some cases, it may indicate other hematological conditions, hence the importance of a thorough medical evaluation if symptoms persist.

A sore throat that lasts more than 10 days no longer resembles the symptoms of a typical sore throat. The symptoms evolve and may intensify, requiring special attention.

Pain sets in: Instead of subsiding, the sore throat remains the same or worsens. The pain may extend to the ears, radiating through the jaw. This sensation may feel like an ear infection. It is then advisable to see your doctor for an accurate diagnosis. This radiating pain is due to the shared innervation of the throat and ear by the glossopharyngeal nerve.

The fever persists or returns: Unlike with a typical strep throat, where the fever subsides quickly with treatment, it may remain high or recur intermittently. This fever may be accompanied by chills, night sweats, and extreme fatigue.

Swallowing becomes increasingly difficult: Swallowing becomes a real challenge, even for liquids. This dysphagia can lead to dehydration and significant weight loss if it persists. 

Bad breath develops: Persistent bad breath may appear, linked to the lingering infection and secretions accumulating in the tonsils. This bad breath is often more noticeable in the morning upon waking.

The lymph nodes remain swollen: Cervical lymphadenopathy persists or even worsens, indicating that the infection is ongoing. These lymph nodes may become very tender to the touch and sometimes visible to the naked eye.

Intense fatigue sets in: The body, exhausted by the prolonged fight against the infection, exhibits significant weakness that can persist for several weeks after recovery.

If a sore throat lasts longer than 10 days, it’s a sign that you need to start monitoring it closely. In the case of a bacterial sore throat, it’s important to see your doctor again if symptoms don’t improve within 72 hours of starting antibiotic treatment.

Even with proper medical treatment, there’s a lot you can do to help your body recover. Here are our tips.

1. Get plenty of rest: If your sore throat has lasted more than 10 days, it’s important to make sure you rest. Prioritise quality sleep—this will help your body recover better and rebuild a strong immune system. You don’t want to get sick again.

2. Stay properly hydrated: A sore throat irritates your throat, so your fluid needs are higher than the usual recommended 1.5 litres. Drinking cool water can help reduce pain when swallowing. Mix it up: water, warm herbal teas, mild fruit juices… Avoid alcohol and coffee, which can irritate the mucous membranes and cause dehydration.

3. Adjust your diet: Even though eating can be a challenge due to the pain, it’s important to maintain your strength. Opt for cold, smooth foods: yoghurt, fruit compotes, ice cream, and cold soups. Enrich your dishes with cream or butter. Break your meals into smaller portions; it’s better to eat less and more often than to skip meals.

4. Soothe your throat: You can chew soothing gum or prepare yourself some thyme tea, known for its anti-inflammatory properties.

5. Follow preventive measures: It is important to protect those around you and the most vulnerable people (young children, pregnant women, or the elderly). Wear a mask if you go out, wash your hands, and do not share your personal items.

If your sore throat persists, monitor your symptoms. If your condition worsens or your fever continues, see your doctor. Do not use leftover antibiotics without your doctor’s approval; doing so could contribute to bacterial resistance to antibiotics.

Don’t hesitate to visit a pharmacy for a screening to identify the cause of your sore throat (viral or bacterial). This will allow you to schedule an appointment with your doctor to start the appropriate treatment without delay. If your immune system is compromised, you can take a course of royal jelly during high-risk periods to support your immune defences.
