Hello As you mentioned in your query that you are very prone to allergy . Let me explain about few facts about the allergy as now a days most of patients are prone to allergy . Predisposing factors responsible for allergy are , hay , dust , fine dusting powder, pollen , mold , sudden increase or decrease in temperature , humidity , fodder etc. If possible please avoid these factors. In allergy usually these develops bronchoconstriction , hence cough ( usually dry , if infection together productive cough ) . As you mentioned that there is pain in throat , so this pain may be due to either INFECTION or ALLERGY. When such type of patient visit in my clinic I advise them to take monteleukast+ bambuterole tablet once or twice in day according to severity of infection and allergy & symptoms . Usually patient responds very nice . If infection also present I prescribe them to take levofloxacin 750 mg once in a day for 5-7 days. Since this is a prescription medicine so please consult your treating doctor . Hot saline gargles and hot coffee is also very much effective. Hope this information will help you.
