Over the past few days I have had this pain in my lower back, right above my ass. I just want to know if I actually pulled something during a deadlift or if its just the famous "back pumps" everyone talks about, I have been taking 30mg of P-Plex for about 2 weeks. Its pretty good when I lay down, but when I sit for a little while and then stand up the pain is pretty intense. Is this a typical back pump?
