@silvern12, I think pain in the calves when you have neuropathy is not uncommon. Many members have shared their experiences in different discussions. Here's a link that shows the discussions and comments - https://connect.mayoclinic.org/search/?search=pain+in+calves+%2Bneuropathy.

It's good that you have discussed the pain with your cardiologist to insure it's not caused by a blood clot. I'm assuming the pain you are describing in your calves is not related to exercise but here is an article that discusses possible causes.

Did your cardiologist provide any suggestions or thoughts on possible causes?
