A throat problem lasting 45 days with fatigue, phlegm, and a dry cough is not typical of a simple infection. This often means there is another cause that has not been found yet, such as post-nasal drip from allergies, a sinus infection, acid reflux, an asthma-related cough, or sometimes a stubborn bacterial infection. If your symptoms are not improving with the same treatment, it is a good idea to have your condition checked again. Taking medicine for a long time without knowing the exact cause may not be helpful. Your doctor might need to see you again and could suggest tests like a throat exam, chest check, allergy tests, or a reflux assessment, but only if needed after a careful evaluation. Do not continue or change your medicines on your own. You can help your recovery by staying well hydrated, doing steam inhalation, and using saltwater gargles to soothe your throat. Try to avoid cold drinks, dust, and smoke. Eat light, non-spicy meals and get plenty of rest. If you notice weight loss, a persistent fever, or your cough is getting worse, please see a doctor soon for a thorough check-up.
