may sound weird but you could try intense cardio, get your heart rate high as you can and keep it up for like 15 minutes a day

i suggest this bcause on a long six day bike trip i started to get carpal tunnel, and getting heart rate up seemed to make it dissipate right away

increaed blood flow and oxygen helps nerves to regenerate is my theory

theyve actually seen this in studies of the hippocampus

also consult internet or nutrition specialist on supplements that can help nerve regenration

i know alpha lipoic acid is available in vitamin shoppe and stroke victims take it ...

dont underestimate power of nutrition and exercise it really might help you
