Over the last 6 months at least Ive been going back and forth with a lower back pain. I have yet to deal with any kind of serious injury from lifting outside of the normal aches and pains (been lifting for 5-6 years). I hit a shoulder session with a buddy at the gym whose a lot bigger than me so I trusted his workout plan. We ended up doing a shoulder press on one of the guided free weight press setups that we have at the gym, but his idea was to spin around instead of using the seat to lean against to try to hit a slightly different angle on the press. Doing so I think my back my have slouched during my set and I tweaked my lower back. I assumed this was like my other aches and pains where it would run its course and go away eventually but over 6 months later here I am still dealing with it. It feels like more of a compression in my spine in my lower back when I aggravate it lifting. Ive aggravated it doing squats, Deadlifts, and shrugs... All exercises where its easy to see that a compression issue could happen. For the next few days afterwards it feels more like a weakeness in the lower back than a compression. Ive had buddies watch me lift to make sure my form was staying clean and there werent any issues there. I have one of the real nice thick 4" all around Rogue belts but this doesnt do anything to help with lifting. The strange thing is that some days I can Deadlift or Shrug 500lbs with no issues at all, other days warming up on something light like 225 lbs I end up tweaking it. Im not a fan of going to the doctor because they love to tell you "If it hurts dont do it" and not lifting isnt an option for me. Any suggestions or tips would be greatly appreciated.
