Since my last cycle my arm delt area been painful time to time. i been doing vitb12 but avoid my left arm fig it was a muscle injury. So today I injected vit b12 into that arm that hurts. After i pull the needle out nothing brown puss looking oil came out. Not blood but thick puss looking it kept coming out pain was gone. But i poked again more came out. kinda worry now, feel a little bump their maybe more not sure. should i go the doc or keep draining? last thing i want to get fuck up. What did i do wrong its just that arm only. I felt since my last pinn.
