Same here Abcess in crook of Arm
My daughter was on a 3 month Meth binge recently, and even though we talked daily, I thought she was doing alright. She then tells me one day, she has been bit by a spider, is running a fever and just wants to sleep.. I finally convince her to go to ER, she goes and comes home for money for Scripts.. I ask to see it and it is an abscess the size of a tennis ball in the crook of her arm.. I knew right then and there her reluctance at going to ER was her own concerns about being judged. She finally admitted to me, it was a "miss" when they miss the vein and the drug is deposited into the muscle.. It can be come infected easily and causes these abscesses.
Don't let his pull wool over your eyes... be tough and strong.
