Ok well iv notice that i have a little lump on my delt and i always inject in and around the same area there, what i thought the lump was is a build up of fluids mainly blood prolly like a bruise. I just injected before and i noticed the viens in that arm blowing up feeling really tight, i than took it out, only injecting half of it cause i thought i hit a vien and was pumping the viens up but that wasnt the case cause i didnt get the symptoms of coughing. I than injected again above that spot a tiny bit and same thing again could it be that its pushing the fluids into my vien or somthin?
