Living with Degenerative Disc Disease and Sciatica: My Laminectomy Journey

Hello, I have Degenerative Disc Disease, Spinal Stenosis, Osteoarthritis of the spine, and possible Scoliosis. I had a Microdiscectomy on L5/S1 back in 2018 due to a bulged disc that was causing sciatica. At that time, the pain was awful but I could still walk. I just couldn't bend over or sit in certain positions. That surgery basically cured me. I was fine up until the second week of April 2022. One morning I couldn't get out of bed. My back had been a little sore for a few weeks but I thought my. Ed was too hard. But the morning I woke up and couldn't hardly move, the lower back pain was excruciating. I made an appt with my orthopedic surgeon. He did Xray, MRI, and a Spect CT scan. The results showed a bulged disc on L4/L5 this time. The pain began to worsen and it became harder for me to walk. I eventually wound up having to get the nurse staff to wheel me in on a wheelchair. The surgeon's PA suggested that I get a spinal epidural steroid injection directly into the sciatic nerve area at my right hip to help. It was wonderful for the first 2 days. No pain what so ever...even after the anesthetic had worn off. I went to work the next day like a newborn baby. On day 3, I could not get out of bed. The excruciating pain woke me up at 5 am and I called out of work. I had been out of work and bedridden for a week from the pain. Fast forward to today (June 12, 2022). I am now completely bed ridden from the sciatica. I literally cannot walk at all and the pain is beyond excruciating. It's completely unbearable. The surgeon placed me on Gabapentin and Prednisone and I take those along with Ibuprofin and Tylenol along with an ice pack. It knocks the edge off as long as I take them all constantly. I am scheduled for a Laminectomy on July 8th 2022 now and that is the soonest he could get me in for the surgery. He knows I can't walk and that I have severe pain and that my entire leg goes numb and tingles and cramps up all the way to my toes. The sciatica is just UNBEARABLE. So here I am waiting on this surgery. I have no idea what to expect. I am terrified. Has anyone here had a laminectomy before? What was your experience? Has anyone had sciatica this painful before? To the point that you can no longer walk? Can anyone tell me what to expect? I'm worried that I may have complications or that the surgery won't help and possibly make things worse. My mind is running away with me. Any comments are appreciated. Thanks.
