I will be having a lumbar fusion early next week of the L4-L5. I have waited a long time for this and have gone through many sessions of PT and pain injections. My doctor says that the back brace is essential to my healing correctly. The brace will support the muscles that have been cut in the process of the surgery. My pool days will be over for the summer.But to be free of pain will be worth it. Wish me luck.
