Thanks so much for the replies.I will try Ed Gee's suggestion on the iron supplements.Also will ask my Dr. about the oxygen concentrator,sounds like a combination of treatment might produce the best results.However I like rv2 go;s suggestion the best,LOL. I did however have my Dr. prescribe a blood pressure medication once. I don't remember what it was called but he said it also helped to expand blood vessels and increase blood flow thus oxygen supply to the body.I was unable to take it because of a side effect so I don't know if it would have helped or not.Thanks again for the suggestions, please keep them coming.
