This symptom I find very strange.... any muscle could be involved but they seem to instantly get so tense causing pain - and nothing really seems to help. It can really make me feel quite low sometimes..
I use Muscle Mag by Wellness Resources - I buy it off of Amazon. When I go off it random muscles tighten up causing pain. Drives me crazy and causes fear.
@A MyFibroTeam Member, yes I take magnesium. It’s recommend for people with fibro. Here is just one article about it.
No, I do take turmeric, garlic and bromelain as I heard they may help... has magnesium helped you??
