Recurring cold and throat congestion for many days with no relief despite medicines may not be a simple infection and can be due to allergy or airway irritation. Avoid taking further medicines on your own and focus on warm fluids, steam inhalation and proper rest. Keep your room clean, avoid dust and keep your head slightly elevated while sleeping to reduce cough at night. Consult your doctor for proper evaluation and a more suitable treatment plan.

A dry cough that continues for a few weeks after a viral infection is quite common and is usually due to irritation and increased sensitivity of the airways (post-viral cough), rather than an ongoing infection, which is why antibiotics like azithromycin often do not help at this stage. The cough typically improves gradually, but you can manage it by staying well hydrated, using warm fluids or steam inhalation, and taking simple cough suppressants or anti-allergy medicines if there is associated throat irritation or allergy. Avoid smoke, dust, and cold air, which can trigger coughing. However, if the cough lasts beyond 6-8 weeks, worsens, or is associated with symptoms like fever, breathlessness, wheezing, or weight loss, you should consult a doctor for further evaluation (such as a chest examination or X-ray) to rule out other causes like asthma, acid reflux, or secondary infection.

Severe throat pain while swallowing food and even saliva can happen due to a strong throat infection, tonsillitis, viral illness, ulcers, acid reflux, or sometimes swelling around the throat area. If you have already used Cefixime with clavulanic acid and Azithromycin without improvement, it is important not to keep changing or repeating antibiotics on your own because the exact cause may not be bacterial. Try to take warm fluids, soft foods, and warm salt water gargles several times a day to reduce irritation. Avoid spicy food, smoking, alcohol, and very cold drinks for now because they may worsen the pain. Rest and proper hydration are also important while the throat heals. Pain relief medicines should only be used after proper medical advice, especially if symptoms are severe. Please consult a doctor, especially if you develop fever, breathing difficulty, swelling in the neck, white patches, inability to swallow properly, or symptoms lasting for many days.
