<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have constant post nasal drip after a slight cold. it does not respond to any allergy meds or cold meds. it causes a severe cough. been like this about 8 weeks now. also have night sweats and am having sweating even in cool room s. I seem to wake up at night and my pillow is wet several times a night. I am 71 and feel generally pretty well.  <response>: Respected user, HiT hanks for using Chat Doctor.come have evaluated your query thoroughly. This is definitely upper respiratory tract infection with some type of virus not responding to usual allergy management protocols. Suggestions for better recovery-Inhalation of vapors of boiled water with added tincture Benson with blanket covered over the head each session of 5 min. 3 times a day.- Gargles with salted lukewarm water and added peppermint oil 3 times a day.- Deep breathing exercises with YOGA.- Avoid cold beverages, excess sweats, spicy.- Plenty of liquids with balanced nutritious diet.- No smoking or alcohol.- Maintain room temperature . Hope this will help you for sure. Welcome for any further questions. Regards dear.
