Well, Perna, I can't truly think of anything I did. In fact, my podiatrist sold me some inserts when I went whining to him. I do think they help. They're arch supports, and believe me, my poor feet are carrying a lot of weight.
I finally went to another podiatrist. He says I do definitely have a nerve problem in my foot and gave me a sample of some special cream. It worked for three hours this a.m.
I think at least part of this problem come from my spinal ailments. For example, I have a herniated disc at L2/L3 and some pain down my behind and leg. The MRI report says the disc is "impinging on my nerve root."
I am scheduled to see a PT doc later in May. Meanwhile, a spine surgeon is supposed to look over my MRI and see what he thinks.
Thanks for suggesting this possibility, however! I appreciate it!

I hope your legs are better.....
