Hi, I have been on Cytomel for a few months now including the generic initially. I asked to get the non generic since I was sick to my stomach everyday & not feeling well. I have gotten so much worse and my heart races at times when I wake up or during the day & I felt my heart skip a beat yesterday since I have tinitus & I can hear it. The thing that terrifies me is for the past month I need help getting in & out of a chair or up from the toilet since the top 5 of both legs are killing me & in the groin area too where that big ligament it where our leg attaches to our body. Have you ever heard of this crazy ,symptom ? It kills me to initially sit down too.
