<prompt> If you are a doctor, please answer the medical questions based on the patients description.Ive recently had a bad sinus infection - but have been clear of most symptoms for about a 10 days. Beginning 2 days ago, Ive been experiencing airway constriction that has led to difficulty sleeping and apnea-like reactions. This came on suddenly and usually only bothers me at night. However, now on day 3 of this, Im started to get concerned.  <response>: Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per your query you have symptoms of sinus infection at night which are pointing towards condition called sinusitis. I would suggest you to take steam 2-3 times a day to relieve congestion, Chat Doctor. You can also take ibuprofen if not allergic or acetaminophen for pain and swelling. For allergy take over the counter antihistamine
