ok so today in class i was rolling with a bigger guy i say mid 250 all muscle n im 200 pounds with a gut i ended up getting him in a gogoplata but as i hooked fuck under his chin my knee poped i didn't wanna let go so for about another 30 seconds i fought to remove his hand then ended up getting it not my legs kinda stiff when i straighten it ? also i can put both my feet behind my head n sit in perfect lotus so i think this is pretty weird but who knows any one have experience with this type of pain before and if so how do u deal with it ?
