Good evening. I have a lot of bizzare sympotoms and I am ot sure how to diagnosis them. I am sure it is allergy related but wanted to double check. I get headaches that turn into migraine just about every day. I have been having some nausea, usually in the morning. This affects my appetite. I do take a flonase spray, twice a day. I also have excedrine migraine medication as well as Imitrex prescription. I woke up in the middle of the night with a fever and vomitted. I have not had a fever or gotten sick since. No congestion. My stomach (yes stomach, not intestine area) seems bloated or perhaps swollen.
