same problem...
i use the same exact guage terumo syringes...guessin it has nothin to do with the needle, its the frequency of shots in the same location...especially when one shoots fina everyday, even if you rotate, scar tissue and small abcesses can pop up...well anyway, i think i have a small abcess in my right delt because towards my 4th week of fina I focused more on site injecting my shoulders instead of thighs/ass...and everytime i shoot near that tight knot/abcess (whatever it is) i bleed...ive never bled after pullin out as much neither...anyway i stopped shootin there for a week...and the next time i shot there, what i did was: as i sit on a chair id rest my elbow on a table...id grab a slab of my relaxed delt with my other hand(left hand) and carry the syringe with my right..then, id shoot str8 down like a hook with my right hand right into my right delt from the slab im grabbin...i had no probs liek that...and every now and then i'll shoot the rear delt to give it som etime to heal...thats jus my experience..and for my tight knots/abcesses(whatever) from the fina shots..ive been using a heat pad and hittin the sauna at my gym..i work at a gym so its convenient...and its been goin down
