It's tough to describe but I'll give it a go
The feeling it gives is like my upper outer glute & lower back muscles are twisted...
Makes squatting/deadlifting a no go when it's bad, and even kneeling down or bending over to pick something up is a mission
Lately I've been using the foam roller before every session, releasing the IT band after reading that it may cause lower back and knee pain which I was getting.
My knees don't really feel sore anymorem but the lower back and glutes is always lingering... I'm starting to think there might be a pinched nerve or something like that...A few weeks back I was warming up on squats, started at 60kg, next warmup was 80kg, and as I hit the bottom of the rep, I felt a sharp pain shoot up my back from my glute, and that was the end of the session, over before it started.
When I played football I did my hamstrings 5 times, once on the left (then never again) and 4 on the right (1-2 of those were just light re-strains when coming back). Then the year I decided to hang up the boots, I hit the 5x5 program over what would have been the pre season, did no running at all, was squatting/deadlifting 160 for 5-6 reps at about 82kg. Then the start of the season came around and I got the itch, so I pulled on the boot having not trained for it at all, and managed to play the entire season without a hamstring injury (I'd say due to the core strength gained)
Problem now is I weigh more (90kg carrying a bit of a gut), but I'm lifting much much less (120kg x 6 squat yesterday trying not to flare this up again, 130kg x 6 dead with a belt 5th, 120 x 6 without in the 4th set) Pretty frustrating with the constant up and down of weights due to injury, but I'm still in there working away at it... I've always used massage as a cure, but I'm thinking of seeing a chiro for a look over to see if there's any obvious issues.
I also think my right leg is slightly shorter than my right. Not sure if it's directly related, but the bulk of the soreness is on the right hand side, so it's worth a thought.
