I have constant dull headaches above and below my eyes. It also feels like I have pressure behind my eyes. I have been evaluated by an ENT and an allergist and have had a CT scan of my sinuses - nothing has been found to be wrong. The allergist said the headaches could be caused by all the medications I'm taking (I'm currently taking Paxil, Loestrin, Detrol LA, Elmiron, Clarinex, Nexium and Synthroid). Could it be the meds? Could it be neurological? Could it be my eyes that are the problem? (I don't wear glasses and have very good vision). I don't know which way to turn - I just want the headaches to go away!!!!!
