Well i have been to sooo many drs. had so many tests. And basically.. no one can tell me why or whats causing it. I have severe head pressure, and pressure behind my left eye, dizzyness, headaches, heavy fatigue, sometimes nausea, constipation and diheara vary, just feel sluggish like i have the flu. My family dr. claims its depression however i was on 3 differnet ones and those didn't help....and i really am not depressed, i jsut want to get better. I allllllllllllways get misqueto bites. I think im actually the main attraction. WHen i go outside to work on my car i usually get bit like 20 times. Its insane. What tests should be run. Or how can they tell if i have this. I've never had a fever. So i probably don't have this. Onces again im just grasping at straws right now.
