I've had back problems since 1955, total fusion in 1972 except for lowest 2 vertabre and disks, still have lower back pain, currently on fentanyl patch. The sensation in my foot extends from the front pad of my foot, where my toes attach to the foot to the heal of the foot, as I've i've stepped on ice and slid some, but nothing there to have caused issue, I actually almost fall, it started with right foot, now occasionally on the left as well, make it difficult to walk, also have deep groin muscle pain in legs, weak musculary feeling in legs,
