Really appreciate your response. I currently take Toprol for blood pressure and "palpatations", do you know if Toprol and nifedipine are similar drugs? I tried to search online for the answer but admittedly I am not up to speed on all the terms and just couldn't figure it out. My hope is that Toprol does something different and I still have a chance that Nifedipine might provide some relief for me. In spite of the pain cocktail that I am on I have to say this week was not very much fun pain wise so guess I have now figured out that even though I take a huge amount of pain med's each day there are still break through periods of pain. Trying very hard to feel better by Easter, I have four grandchildren counting on me to hide their eggs all over heaven's half acre!
