Welcome @martyo321, I've also been dealing with the numbness for over 20 years. It's been many years since I've done any jogging, I'm the same age and can probably do a speed version of the senior shuffle if I'm crossing a busy intersection which I try not to do very often. You are doing great if you can still play tennis. We are definitely lucky to only have the numbness. Even though I've had the numbness for a long time, I didn't seek a diagnosis until 2016 and found out I had idiopathic small fiber peripheral neuropathy. After which I was told the same thing my primary care docs had been telling me all along, there is no cure and there are no medications that will help with the numbness. So I turned my focus onto learning as much as I can about the condition and what treatments may be available to help.

Have you done any research on your diagnosis or type of neuropathy?

Great to hear you have been able to "live" with this and no pain. My symptoms are as you described but numbness is creeping up my legs but I'm still very active at 70. Do you remember what kind of toxins your doctor found and what was process for getting rid of them

How is your balance? Especially going down public steps with no railing?
