When I had an allergic reaction to
Copaxone after being on it for a couple of years I went on Betaseron. Now, for a couple of years, I've been having strange feelings with my heart - the fluttering associated with Afib, slight pressure, thudding beats I can feel, especially at night when I lie down to go to sleep. My doctor says to put up with it, but it scares me with the bad heart history in my family. Has anyone experienced this and what did you do?
