Hi, i made thread also yesterday how ive been using same dull needle since thursday bcs the holidays so the needle exhchange isnt open till tomorrow. I shot buprenorphine, which was filtered with old sterifilt and found very hard to register vein, and didnt got any blood out even in new spots i tried to hit so that got me little concerned. Is that normal? I always stop pushing if i feel pain, irritations or anything and i know im not in vein, but after awhile i hitted old spot, was pretty deep and slowly pushed the plunger, didnt felt any pain, it didnt felt like i wasnt in vein so i just go for it. Afterwards, i started to think that was i in vein after all bcs usually the site has always swelled, been hard, got lump or smthing. But the site doesnt really show any ”symptoms” from missing, but im still thinking bcs i couldnt register and the needle is old, would it be that i still miss? Can missed shot show signs later? The site is pretty scarred, i can put a picture above and it feels hard, but it does like every dull needle hit i have in my arms, i think those are just scartissue. Thank you if you respond and have some insight, and sorry if this is asked before! Just little concerned, lately ive been reckless with the hygienw and stuff, im pretty hypocondriac so i always assume the worst and think i have like enthecorditis or sepsis now or abcess
