Sorry for all of you who suffer from this terrible affliction known as Peripheral neuropathy. I have been dealing with it for almost nine years. It has worsened in the past nine months, now moving into my legs and feet.
As most of you have stated, no specific cause can be nailed down yet. Hence, the term "idiopathic". I usually mention to every doctor I have seen(is it eighteen or nineteen?), for every effect(pain and numbness), there is a cause. We know the cause is, to some degree, nerve damage. But, how do we treat the nerve damage? I had a spinal cord stimulator that worked fairly well for a little over two years to mitigate the pain. However, it was just a bandaid(as are the various meds I'm taking). Bandaids usually fall off after a while. The underlying cause needs to be discovered. If only the medical field would devote the time and resources needed to find that cause, those of us suffering would gladly pay whatever the cost would be to get out of debilitating pain that keeps us from enjoying life.
