I have been taking Copaxone injections for Multiple Sclerosis for the past month and a half. Last night I had my first post injection reaction–you know, the one they warn you about with chest tightness, flushing, difficulty breathing, anxiety, hot sensation and so on. Has anyone else experienced this? I am afraid to start back with my injections. I wouldn't want to go through that again–I thought I was dying! Anyone have feelings on this?
