I'm about to be 20, 5'8 175 8% bf training 4years. Have managed to get a 405 box sq before all my leg injuries, i cant even do 135 now. I have a very deep, sharp, nagging pain inside my left inner groin/hip flexor area which has increased tremendously in this last year. I believe i originally aggrivated it about 2 years ago doing decline heavy abs, i felt a pop. Not much pain then, but about 8 months ago i blew out my knee in the army and couldnt bend it for 2 weeksish. Once i could walk again, i noticed my left groin(same side as my injured knee) was seriously tight. Never mentioned it thought, but now its in the way and pretty painfull.
I've iced it, massaged it, rested it, and stretched the hell out of it. I've had to seriously lay off my kickboxing this whole year, and stayed far away from squatting. No matter the stance, wide, narrow it all hurts this area and makes deadlifts difficult as well. Even the stretches are difficult to perform. I've just recently got insurance, so ill be getting an MRI soon. I'm wondering if anyone could possibly inform me of what this might be, what to expect, and how long the healing process is?
