Could you explain inflammatory sinus disease of the right sphenoid and mucoperiosteal thickening of the right sphenoid sinus. These are the results of an MRI I had due to a very awful headache I had in one spot (right side of head). After the headache I developed ear pain, eye pain, and dizziness-- all on the right side. I haven t had any typical sinus issues, no recenr colds or runny nose or anything. I am 25 and this is my first ever sinus issue. The headache started 2 weeks and 3 days ago. I have been prescribed 60mg prednisone for 5 days then tapering off for 10, 8 day course of amoxicillin,and flonase.
