Hi there ~
I understand your concerns. I believe that the bruise
on your inner thigh is a result of having used a bad site to inject yourself with heroin
into the groin vein. I believe that you need to consult a doctor to get treatment for the thrombophlebitis
that has resulted from such injection. The use of IV drugs may be lethal and I suggest that you consult a psychiatrist
who can advise you wisely regarding the ill effects of these drugs, their potential lethality and the possibility of your having to go to rehab for recovery.
I hope this helps. Take good care of yourself and have a lovely day!
