For about 5 weeks now I have been having problems with shaking and weakness. It all started with shaking in my hands. If i'm resting it's fine. When I start doing something like fold clothes my hands and arms start to shake. They then become sore, then weak. This takes hardly no work at all to do this. I am an active person and have not been able to work because of this. This also happens in my legs, abdomin, and jaw. It's really weird. I have had multiple blood tests which show normal. They have checked for lymes, thyroid levels, calcium, potassium, and others. They all come back normal. I have also had MRI's done on my brain and cervical spine looking for lesions and they come back normal. I have also had the muscle test where they put the needles in. Sorry I don't remember what the test was called. The doctor thinks it viral but it isn't getting better. Has anyone else had these problems where they have had all these tests with nothing. Please help.
