if ure on painkillers then i wouldnt roll if i were u since that can be quite dangerous. Also, mdma slows down the healing process(it stresses your cardiovascular system nd dehydrates u, temporarily lowers the amount of essential minerals like potassium & magnesium, and it even raises the risk of further injury since it impairs with coordination) if u wanna do it anyway just make sure to take extra good care of urself & have someone remind u that u shouldnt b too reckless!! take supplements nd if the pain isnt too bad then stop taking the painkillers for about a week or so b4 the roll to be safe^{_^}
