I know it varies from person to person but those who have hypothyroidism-do some of you have strange muscle twitches, or beats under your skin, in your muscles? I have had this since last summer. The doctor doesn't seem all that concerned yet. I also get this pain in my right calf-usually more so that time of month-and I had never heard about water retention in hypothyroidism until today. How can you tell? What is done about that? Is this in more severe cases? I was diagnosed on May 18th so I am still educating myself.![]()
