Walt, I know about your surgeons' refusals, but your wrote a couple of days ago that you had an appointment with a new doctor, and were going to try that one for a prescript, and were going to go armed with that pdf printout. Have you tried that one yet? I just don't know why these surgeons of yours don't want to prescribe the nifedipine, unless they are worried the nifedipine works too well and will keep you from being a paying surgery patient.
My surgeon didn't have a problem prescribing it, as it is along the same lines as the nitroglycerin, but doesn't give the headaches and has a much higher success rate. I have had no side effects at all with it either of any kind, so I am very happy with this. The nurse told me I may get low blood pressure, but that hasn't happened in over a month---I make surre not to use more than a BB size dose, and that seems to work well. I would seriouslyl question the motives behind your surgeons refusal to let you try this treatment.
