Months prior to be diagnosed with PMR, I use to get leg cramps in my right leg thigh and calf. I started taking 250mg of Magnesium Malate powder every night and that seemed to do the trick. I have been taking 15mg of Pred. for 5 weeks and starting to get sporadic cramps in leg muscles I have not heard of, like Tibialis anterior, front of leg next to chin bone, by God that hurts, had to get out of bed put the massage unit on it followed by hot wheat bag! I am also getting some cramps in my hands which I never had before., could be lack of water so have upped my intake and continuing the MM. Perhaps this is not related to my PMR or the Pred. Any comments appreciated.
