I get a sinus infection about 3 times a year for the last 10 years. My old doctor would just call in an antibiotic each time. I recently moved and got a new dr. Sinus infections are miserable especially the post nasal drip and the hacking up mucus. My lungs feel so heavy and hurt. Is there anything else I can do to prevent getting sinus infections? I am wondering if I should have this dr refer me to a sinus specialist. What can they do to help? Thank you!!
