Thanks, Frank. An old Aussie saying, now rarely heard as not PC, I must have run over a Chinaman...(bad luck). Cellulitus and swelling in foot led to diagnosis of PAD (2 angioplasties).
Regular cardiologist notified, if Jim is plugged up in leg, his heart is as well...so CT angiogram and then catheter angiogram w/coronary stents placed...and now the colonoscopy...a lifetimes (69) worth of maintenance in 5 months. Oh well, that's what insurance and our single payer healthcare is for. I'd hate to drop off without getting my 2 bobs worth! Thanks for your thoughts.
