My lower left back has been sore, so I’m doing standard rehab work - graded exposure with exercises and weights that don’t make it worse. The issue is that sometimes the back muscles will grab (contract painfully) for a few moments while exercising (at which point I stop the set). Soreness goes back to baseline shortly after I stop a set. I haven’t been able to find a useful entry point so this doesn’t happen. It’s even happened occasionally with sit to stand from a chair.
Does this phenomenon suggest some course of rehab other than just enduring a few moments of pain on some sets and proceeding so long as I don’t feel worse later?
