Has anyone had a sinus cyst? if so did you have surgery and how was the recovery? I've been on antibiotics on and off for like two years for sinus infections. They ordered a CT scan and found a large cyst in my right sinus, it's big enough that its moving stuff around in there. My head and everything in it hurts all the time. I'm worried about recovering because I'm on Methotrexate and my rate of healing has slowed considerably.
