Can anyone tell me if "physical therapy" has really helped them after a fusion to L 3/4 & L 4/5? Had the fusion in June, 2010. Had screws removed August, 2011. Cage is still in. I'm 61, and will be having therapy for a frozen shoulder at the same time as the fusion therapy. I still need a cane to get around and cannot stand for too long. I'm wondering if I'm just going to be adding more pain to what I already have.
