I'm on Copaxone second time around. Did 7 mo. was not helping. Went to Tysabri 8 mo. felt great, but, had 20 skin cancers cut off! (Tybabri promotes skin cancer if you'r the type). Doc said stop Tysabri, and go back to Copaxone(last 6 mo.) The big red welts, and pain or itching ranges from minor....., to major......!!! DIFFERENT EVERY DAY!!!!!....
