multiple sclerosis
"I've been on Gilenya for 5 months. People posting on blogs seem very concerned about the initial drop in heart rate. Mine dropped from 86 to 66 within a few hours and then went back to normal. They said that if it falls below 55 you just have to get up and walk around until it goes back up, so it's not as big a deal. I have had no other side effects and am thankful that I was diagnosed after there was a pill as a treatment option."
