Your symptoms are not related to allergy
and you do not have history of allergies either. Your symptoms are more of sinusitis. I will suggest you to consult your GP and have an X-ray PNS done as early as possible. You are sensitive to changes in weather and your problems can be due to acute cold
. Decongestants can relief you of the symptoms temporarily.
Steam inhalation can be of much help to you. Boil some water in a pot, keep it on a table, open the lid. Cover your head with a towel. Now try to inhale steam through one of your nostrils while keeping the other closed. Exhale through the other nostril. Repeat this process at least twice a day for a week or 10 days and you will get permanent relief from stuffed head and blockage that you are experiencing.
You have to continue taking the oral medications prescribed by your GP. Do not neglect the problem as chronic sinusitis
takes much time to get cured. Your hearing will improve with medications and steam inhalation. Enjoy good health. Take care.
