Hello, I am a 25 year old female who has been using meth by iv for the last 3 months and I am not good with it. I have 3 knots on my right arm but they are different I don.t think I missed because that is very painful and i did not feel any pain at the time of injection. The two that are on my lower arm are sore when you touch them and have a redness and bruising around them The on on my upper arm is painful even without touching it. It also hurts underneath the knot right where u can feel a pulse I have tried ice and heat and I m not quite sure either is working. Now when i pull back and get blood it clots instantly. I have no medical history and i.m not taking any other drugs or medication, but I do smoke a little less than a half a pack a day. Is this a major issue or something I can take care of here at home
