About two weeks ago I experienced new numbness down my left calf, left foot and into my big toe. Now the areas that were numb along the top of my foot are burning...is there any significance in this new burning? This has just recently started in the past few days but it was driving me crazy at work last night, to the point that I had to take off my sneaker and socks to get the pressure off for a few minutes. I know that my ESI & Medrol dosepak are wearing off as my sciatic pain has been increasing since Thanksgiving. Does anyone have any helpful advice on this? I'm not currently taking anything for nerve pain since the Elavil didn't work for me and I've been able to tolerate my nerve pain since taking the Medrol dosepak two weeks ago. It feels like I've burned my foot with hot water!
