True, no cure so far. Luckily I don't have pain, but numbness. It looks like dizziness may come from drugs side effects. Originally the the numbness was attributed to Lumbar stenosis and afterwards to diabetes. I have declined surgery. So far exercises and physical therapy do help, but not a lot. I can not walk stairs, don't drive anymore. Do supplements help? Are there any unconventional alternatives?
