I have done my medication with a neddle 4 times and my hand is now swelled up and hurting really bad.I had missed about a week ago but not all the meds I stopped when I realized I was missing and its just had a little knot and that was about a week ago. Now just today it has swelled up the size of a golf ball.it is swelled up and puffy all around it. I think it may be gettig worse as I'm spending time online trying to find a site to ask a nurse or chat with a nusre/doctor and all I can find is ones where I have to pay $50 or more.. what do I do or what can I do. Do I half to go to the E.R. Also I missed in the bend of my arm and its been the size of a golf ball and as hard as a rock what do I do? Can I slice it open myself and let it uuzzz out?
