that is weird because the same thing happened to me. But I have a lot of pain in my joints and fingers. My Dr. Said that is a sign of low thyroid, he did test my blood and my thyroid is very low . So get a thyroid test but make sure they do the right one because they have several different thyroid test. I had a thyroid test done by another Dr a month ago and she said it was normal, so make sure they do the right one. Good luck.
