ok... i did my usual shot of sust in my tri and right after i was done i noticed my arm went numb for a bit right below the site of injection... its not 5 minutes later and below the injection is all purple and it looks like i got hit in the arm with a bat. what do i do??? should i go to the hospital... wait it out? could it be an infection. It's pretty ****ed up looking so please help.
