<s>[INST] I missed a vein while slamming meth in my forearm about a week ago and it swelled up my whole forearm bad. today the abcess popped and i squeezed out a lot of puss and blood and it even looked kinda oiley. now when i push on the skin around it what looks like a big puss pocket pops out of my skin and goes back in as soon as i let go,but the bubble looking pocket is black and when i pull on it, it will streach way out but wont come out im worried it might be dead muscle tissue what do you think?
