I already was having lower back pain on my left side all the way down to my toes, my MRI showed I had Sciatic nerve proplems. I started taking a low dose of 15mg in August, and then it increased in September, well my leg pain started the end of August, it feels different from what I originally got my MRI for, this pain usually comes around the time of my menstrual cycle, it is a sharp, nagging, pounding pain from my leg all the way down to my toes and my toes tingle, especially when I'm laying in the bed at night.
