Stretch,
Curiosity on my part with the following question. Have you been diagnosed with peripheral vascular disease? The reason I ask is because I have diagnosed PAD/PVD and also have ischemic build up in the abdominal aorta which will most likely lead to an aneurysm, all of which is being monitored by VA vascular specialists on an annual basis at this point. I didn't pick up on whether your PCP had you referred to a VA vascular specialist to monitor you on a regular basis. You have been given some excellent advice by Carlie, JBasser, Berta and others. Please stay on top of this and follow thru outside the VA if you don't feel secure in your treatment at the VA, OK?
Best wishes with all of this my friend!
