i've already had a hernia operation when i was like 6(now im 17) and for the past two months or three, i've been going to the weight room at school getting in shape. Now, my mom just recently told me that i can't work out a lot because then i'll get another hernia. Is that true? and how would i know that i have one or not?

After my mom told me that, i've been noticing something pulsing down there and for a couple days i've been feeling sort of a cramp/pain that went on and off. But then again, i could be paranoid and the pulsing and cramp thing could just be in my mind being influenced by what my mom had said.

so....any thoughts. Can i really get another hernia?
