Thanks everyone! You guys (and gals) really are a great group. I had a long talk with the doc about it this afternoon and he had prescribed Cipro a while back. I haven't taken it because my fluid intake wasn't good enough (at the time). He thinks I have an infection in my Eustacian tube. The head & neck surgeon sees fluid behind the eardrum. Sometimes the pain is pretty severe (like sharp and stabbing). It "pops" every now and then, usually when I am exerting myself (it "lightens" up but never goes away completely). I held off because Cipro is pretty powerful and I don't want to take it unneccessarily if there is another solution. I also haven't taken it because my fluid intake wasn't good enough (at the time). I still don't know whether to take it or not. He doesn't think it's cancer either but because it was an anomoly on the MRI, he had to disclose it to me.
