I hate being a whiny person, cause I truly believe Levothyroxin (generic Synthroid) has helped in some ways. However, I am not sleeping, because I hurt. My ankles hurt, my legs hurt, my neck hurts and my arms hurt. There is some swelling on the top of my arms near the elbow. Now this hurt, is not unbareable, it is not extreme, but it is enough that it keeps me awake at night. Is this normal? Does anyone else experience this? I have been on the drug for a month now. I was diagnosed with Hashimotos disease after they did many tests, and also found a goiter, and found that my thyroid was not doing its work. I am uninsured, so am paying my way thru all this testing, set up on payment arrangements. I was very thankful the medication was affordable. I am trying not to go back to the doctor so I thought I would see if anyone is experiencing, or did experience this? If it is a common side effect? I am hoping it goes away in time?
