I've been plagued by a curved spine that switches curvation for two months. It was a herniated or bulged disc in my back and it would impact my sciatic nerve causing sharp pain in my left gluteal region and aches down my left leg. I came into the library and my spine was the most curved that I had ever seen it. I haven't been able to even run and I've had to walk like an old crippled man. It just turned perfectly straight I noticed when I sat up after hours of work. I hope it stays!
