For several years now I have had diffuse muscle cramps, these involve all muscle groups(30 fifferent muscles groups. They seem to cycle they will be very bad up to 25-30 duifferent muscle cramps throughout the day for about 8 days then they decrease to 4-5 per day then in about 3-4 weeks the frequent crams begin again. The most painful are behind the shoulder, hamstring and inner thigh. the most frequent are forearms, calf and shoulder including biceps triceps deltoid. I have been evaluated By GP, neurologist, neuro physiologist, physical therapy, It is not tumor, MS, fibromyalgia, autoimmune or metabolic all blood work and MRI WNL.Any thoughts on this?[/enc]
