My spouse has been having extreme weakness and tiredness (all times) for the last three months. She feels weakness in the legs (above knee), trembling hands, vibration feeling inside the body, shakiness. Except for hypo-thyroid she doesnt have any other condition that we know of. We recently did blood test and everything seems normal except for iron and vitamin D insufficiency. We had checked a couple of neuro surgeons and they suspect that it's not related to neuro and it could be related to thyroid. So for the last two weeks she has reduced her thyroid dose from 100 mg to 50 mg now. Her symptoms are just the same over the months and we are still not able to figure out the actual problem. Would appreciate if you could let me know what the root cause could be? Thanks a ton in advance!
