While my sciatica (and I am assuming it IS sciatica) started with the usual symptoms - pain in the lower back shooting down my leg to my knee - the symptoms have evolved into something new for me. Most of the lower back pain is gone, but the inside and front of my left leg is now so tender, wearing pants hurt. At night, moving the sheet causes pain as it moves over my leg. I also feel a stiffness in my knee, and sometimes an almost electric shock that can be very painful going through either my whole knee or just the inside part. I am now three weeks into this bout. I am taking percocet and celebrex. The percocet dulls the pain somewhat, but not entirely. Has anyone else here had this tenderness as a symptom of sciatica? It has me very worried something else is going on.
