glad to hear you got some relief azalea!
clarification - since you were prescribed a muscle relaxant, after experiencing symptoms such as chest tightness, headaches in addition to pain, that ties in with my leaning toward magnesium in the post above.
but, you mention getting relief via zinc. that is interesting - can you confirm you did in fact mean you are taking zinc for the pain, and not magnesium? or are you taking both?
either way, really awesome that you have relief from pain
ps never heard of the ms hug - what a newb lol
