Thanks for the update, I do not have any other symptoms like lung disease or such, just have the tingling in the feet and pain at times. Have been checked out several times I do not have diabetes or any other problems aside from an enflamed knee which has a torn muniscus slight arthritus and one other torn ligament or such can't remember, all in the one knee so have inflamation, all of which is causing problems and pain, but have decided no matter what going to get back into my exercise routine as I miss the strength in my legs so will see what I can do. Nothing seems to be helping as far as meds and I am not one to take pain meds on a regular basis, I need other alternatives which will help, but the foot pain is more concerning right now as it does not let me sleep. On a regime of B vitamins since august but does not really seem to be helping.
