Is this even possible?

Thanks so much for taking the time to read my post. I am curious to know your thoughts on what happened to me.

I am 54 years old and have had no real problems with my back. (Other than a spell of sciatic pain from sitting for a long time on an uncomfortable chair 10 years prior). I started to feel pressure in my lower back and pain in my right hip. I went to a walk in clinic and was sent for and xray. Results came in on a Thursday doctor said nothing serious but wanted to see me on Monday to discuss the results. The next day the pain started to go down the back of the right leg so I decided to go into emergency thinking that maybe sciatica. I go to emergency and sat in a metal wheelchair for 6 hours. The pain got so intense that I begged the nurses for a bed or stretcher to lay down. I was told there were no beds. I sat in the chair and cried like a baby. Ten mins later the hospital found a bed. They took an xray gave me a shot for the pain and a pill to calm muscle spasms and sent me home. As soon as the meds wore off the pain was unbearable down my entire leg and my foot was numb. I went back to emergency 2 more times before I was sent for an emergency MRI followed by emergency spinal surgery for a massive disc extrusion. Surgery went well . I am 8 weeks post op and have bowel control but cannot walk without a walker and still have a drop foot and a lot of nerve pain. My question to you is...is it possible that this was brought on from my 6 hour wait in a metal wheelchair that had no padding what so ever or would I have had CES regardless of what happened with the wheelchair? Please share your thoughts..Id love to hear from you 😊 Warmest regards - Candice
