I am trying to diagnose the cause of neuropathy and circulatory and tingling/numbness and pain problems in the feet. First, I am trying to rule out cervical and lower back causes.

The other physical conditions are disc bulges in the L4-L5 and L5-S1 area. Also a cracked annulus at L5. Also there are post-op cervical disc problems at C4-C5-C6 held by a titanium plate fusion.

If there is no pain down the leg………. And the neuropathy and circulatory problems are localized in the feet …. Does that mean sciatica is NOT a factor. What is the best way to determine what is causing the problem in the feet?
