I injected my left delt for second time and during injection i sneezed and tensed my muscle which hurt like hell but finished injection, when i withdrew needle it leeked blood more than usual but quickly stopped after pressure applied for 10sec. Little pip which is pretty standard with this test e but was below injection site. 2 days later after chest workout i noticed a bruise type lump between bottom of delt and upper outer bicep. What has happened here?
