i hit a blood vessel and withdrew the needle, but some blood came in the syringe, in fact a big clot, so i tried to squirt it out, but still there is a clot of blood. i dont really wanna waste the juice, should i inject it, what im fearing is that if i go ahead and inject and if i hit another blood vessel, i wont know when i pull back the syringe cuz theres some blood in there already. :yellowcon
