@8m5 I think you have your answer. Sometimes steroid injections are done to ease inflammation and that might help if it buys a little bit of space. PT would try to address strength and posture to avoid positional issues that may increase pressure on an already compromised nerve. If the pressure on the nerve as it’s leaving the spinal column is caused by arthritis and bone buildup around it that closes down the space, the remedy is usually surgical removal of the extra bone and/or removal of any bad discs, etc. When a disc herniates, the jelly like nucleus spills out causing inflammation. That can initiate bone spurs to grow in that area and that can be a cause of bone growth in the foramen which is the space where the nerves exit the spinal cord.
