I m two months post thyroidectomy . I m feeling good overall. I had hypothyroid issues for years, very enlarged gland and ultimately cancer which was small enough to be surgically removed. I am an avid runner and resumed activity two weeks after surgery. I m having trouble with shin splints and muscle cramps in my calves. While this probably is an overuse issues that can be worked out with proper stretching, massage and rest, I m wondering if there could also be a link to the thyroid function... Or lack thereof. Just looking for clues that may help me keep my ability to exercise in check. I need it for weight management and emotional stability!
