OK. If you are very worried about it, show it to your doctor and have your thyroid tests done. It also *could be* rheumatoid arthritis (easy to test for) or anemia (also easy to test for, and I am sure one of your normal blood tests for your condition). I have them, and everyone I know over age 65 has them to some degree. See the doctor. Get the tests. Then you will know, versus worrying. 🙂
