Triple Laminectomy w/spinal fusion, now leg pain worsening

I am 77 years old with a long history of back/spine pain and chose to have surgery in March of 2025. It is now August 10th and my leg pain is getting worse. Cramping so bad I loose my balance. Shooting pain in both legs. I have been on Gabapentin again for about 10 days, trying to stay up as much as possible but it's 2 hours up, 2 hours light housework/laundry and 2 hours down (either bed or sofa). My spine was pushing on the spinal cord causing pain and other issues but I thought this would be better than a wheel chair. Anyone else have solutions to pain. I could not tolerate PT and over the last several months my leg strength has gone for really good to extremely poor (post surgery). Arms are also loosing strength and articulation.
