My wife used to suffer a lot of tingling/numbness and burning in her feet. This got greatly reduced about 6 years ago when she started on Prokarin. You can read up on it at www.edmsllc.com
. It does not work for everyone (what drug for MS does?), has virtually no side effects and has had one double-blind clinical trial done on it. Prokarin can be difficult to get a doc to prescribe it because it is so little known. (no big pharma behind it) It's a transdermal patch and painless to use.
