Interesting. I started on Crestor in January (following receipt of a stent for a pesky blockage) and I have had no pain or issues with my cycling. In fact, this year turned out to be my best from the standpoint of mileage and speed. Going back to Dr. Cardio next week for a warranty check.
One thing I have noticed and I don't know if it is from the crestor or Plavix, my fingers are always cold and they go absolutely numb when riding in even cool weather. I sit at my desk with numb hands if the air conditioning happens to be turned up.
