I have been on Fina for 2 weeks and today, for the first time, I got a pump that was unreal. I was working arms and when I started doing forearm curls, after the first set my forearms felt like they were going to rip through my skin. Then after the second set, my entire arms went numb and I couldn't feel a thing. While doing the third set, I couldn't feel anything and I just did them til my grip gave out. After that my arms were hot and tingly and the feeling didn't come back for like 20 mins. Is this something that I should be worried about?
