Last year my body shook and my hands, almost like a Parkinson's patient but gradually it went away. Also, the muscles of my body contract and sometimes is painful and it got to a point were I wasn't able to swallow and had a hoarse voice. It happens but once in a while, so I think is fading. The frustrating part is that nobody understands, including doctors. I've had gone to the ER several times and they told me I was having panic attacks. Frustrating!!!
