What Causes Edema And Muscle Twitches All Over The Body?

Hi, i feel sick for a couple of years now. I feel tired, got edema, have muscle twitches all over my body, problems with eyes an restless legs to name a few things..
My blood tests are all good. Only things is my TSH is a bit high. TSH is 7.2 last time they checked it. They will not give me medicines for it, only if the TSH is above 10..

Could this be a thyroid problem, or could there be some other problem. Thanks!
