I was doing deadlift this monday 130kg x 5 and didnt feel any pain during my sets, but when I was done i felt really "pumped" in my left lower back/tail-bone. And now Ive felt this small sensations in my buttocks to hamstring. Im thinking it might be piriformis muscle that got really tight perhaps, my left leg has a tendancy to be really tight compared to my other leg.
I think it muscular, since its prolly a swollen muscle thats preassuring on my nerve o/s.
and is this a simple rule, if its not hurting, keep lifting? ofc with good form.
thanks in advance
