Hello Doc, Recently I have started having some uncomfortable experiences, whereby firstly I would visibly observe the muscle that exists where my arm folds, jumps for a long while. It could be slightly compared to beating of the heart when it is really overworked, but it feels very different. Now, I get the same throbbing/pulsing feeling on my lower right side. There is no pain, but it feels uncomfortable, like a spams but no pain. Could you enlighten me as to the cause of this? I have my own theories but I am no doctor. Thanks
