Hey guys. So I've been reading through this forum and HAVENT quite found the answer im looking for. I just started IVing heroin a couple of weeks ago. A few days ago, my arm started to feel sore and I have two small red lumps that are line shaped, not round, where I inject on the inner arm behind the elbow. My friend told me it was just scar tissue , and there's also a faint greenish yellow bruise in that area top. Of course I was still injecting there, the last time being last night. But my arm is a bit sore. I can still move and extend it, it's just a bit uncomfortable. I was using a dull needle the last few days to a week , but no more than a week, because I haven't gotten the chance to get to a pharmacy due to work. I know I shouldn't be using dull needles , and I'm not going to inject until I can get to the pharmacy as a safety precaution. I was just wondering if this soreness was normal. Thanks
