you are not alone mate. i can feel your pain. I had backpain and Sciatica for 3 year because of herniated disc. Exercise or yoga that can realigne spine will help better. i was on Gabapentin for 2 years. because of that i used to forget things. its symptoms of Alzheimer. i am using targeted spine release technique every 5-10 min daily. It’s helpful.
Get well soon.
