I have a pain under the sole of my feet since three years ago,and since this disease started I never feel good. Nothing has made me feel good. I had X rays, MRI(lunbar stenosis)but I never feel pain at my back, legs, ankles, etc ,and tests of my nerves done and my arteries work, they are OK. The last Dr. told me I have plantar fasciitis, but the symptoms are not the same. When I'm in bed (resting)all is OK, but when I walk for an hr. the pain increases more and more until I go to bed and wait for a long time.What can I do. Thank you. Mike
