Doesn’t happen everytime but i sometimes feel a sudden rush of blood to the head, tightness of the chest, difficuties to breath and my face and neck area turn bright red. Only lasts for a minute or so, but i end up with a stinking headache after. Neuro says it’s an uncommon side effect of the Copaxone. First time it happened i thought i was having a heat attack. Very scary. It’s happened tonight and i just wondered if it happens to anybody else?
