I had a boil on my leg for about a year I was given antibiotics which would make it go away for a while. I was also diagnosed with depression, I was taking prozac. I thought the prozac was causing fatigue so the doctor gave me effecor. Which at the time I thought was making me dizzy. I went to the doctor because the boil had gotten out of control leaking puss and blood. I was also very dizzy walking in to walls. When I got to the hospital I passed out on a nurse. They operated, cut and drained the boil, ran a mri on my brain, and spin and found out that I had MS. Its been 4 weeks now. I'm still in the hospital, and I'm still dizzy, not as much but I can walk iinto an open room.
