I had a spinal fusion at L5 S1 and a laminectomy on 10/31. Foot has been terribly numb (no feeling). I am on gabapentin 900mg at night 600mg in the am. That said in the last day or two i have started having terrible burning and itching of the foot and awful pins and needles in that foot which is creating severe pain. It is extremely hypersensitive - and i jump and am in pain if anything touches it. Part of the foot (the ball and inside of toes also feels numb). Any ideas what might be happening - as I am totally freaked out by the odd change in pain?
