I'm hoping im posting this in the right area. Not sure if i should say swim or whatever so here it goes. Shot 20 units in wrist a spot I use only sometimes, stung a tiny bit but I was still registered. Afterwards no rush but no pain and a raised lump. Doesn't really hurt and I've applied a warm towel. Not new to IV just only used meth the past few months. No rush or high felt either but didn't feel pain like you do a miss and I wasn't tied off and injected slowly. Any ideas?
