Hi friend. I'm in a similar situation. I was fused from L1 to L4 at age 16 with one rod and 4 screws. At age 21 that rod snapped in half (nothing I caused) and they performed a 2nd surgery to take out the old hardware, then a 3rd to place 2 rods and 11 screws at T11 to L4. I'm now 49, and last year I had to extend my fusion to add my L5 and S1 due to disk degeneration and spondolisthesiosis. At my 2 month check up post surgery after my complaints of painful clicking in my lower back it was found that 2 of my new screws were loosened and had to have a 5th surgery to remove that hardware and instead place 2 plates and screws. That bad boy isn't coming loose again! But that surgery was excruciating. They had to reopen my scar on my back to remove to hardware, but cut me on the front side from above my belly button to my groin to place the plates and new screws. It was the most grueling procedure I have ever had. Afterwards there was a ton of in home PT just to get me mobile again, then I transferred to outpatient PT. They decided I would get the best results by doing aquatic therapy, and let me tell you it has done wonders to increase my mobility as well as core strength. Now I have a membership to my local YMCA and I hit the pool 2-3 times a week to do the exercises they taught me. I never thought I'd ever be able to get rid of my walker, but now I can walk to the end of my street and back with my cane. The cane may continue to be a part of my life outside of my home, but I'll take that after all I went through. I highly suggest getting into a pool. It has done so much for me after basically living in my bed everyday. I wish you the most healing hug. You are so strong just for getting the procedure, and that's a huge fusion all in one go! Don't give up. If I can go from muscle wasting and barely able to microwave myself a 3 minute meal to walking to the end of my street, I know you can continue to heal and increase your mobility too. < 3
