I had 2 stents put in about 5 months ago and started on Plavix.. Since that time, I have had problems with chest pain and stomach pain, along with a host of other pains. I had a second cath to look at my heart because of the chest pain and the heart was said to be fine. Having a hard time sleeping at night and anxiety is building because of the pain. Anyone else have these issues? Also, is there a blood test that can be given to see if the Plavix even works for my gene make-up?
