I am 20 yrs old and I have been Lifting regularly for about a year and a half now. I've notice that when I do my squats which are free standing with weight bar on my shoulders not a machine, that I get this pain in my lower abdomen in a pinpoint spot about 2 inches above the pubic hair line and 2 inches right (my right) of my belly button. Note that I am 6'2'' and 220. It kinda feels like if you were wearing jeans and the button of your jeans was drilling into you when you squatted down. It only happens when I get into my heavier sets too. Does anyone know what this is?
