I had a sinus surgery last April, but have been having problems ever since. It is my third surgery and was quite painful. I just got another CT last week and it shows sphenoid sinus moderate to severe mucosal thickening and bilateral posterior ethmoid and maxillary sinus mild mucosal thickening. Could the previous surgery have caused this problem? Shouldn t the surgery have solved this problem? I have lost considerable weight and have no appetite since the surgery. I also have constant drainage that makes me vomit. I have already consulted with a GI, had an endoscopy, colonoscopy, and barium x-ray. All the results came back normal.
