PAIN BETWEEN the SHOULDER BLADES & CHEST PAIN

I had 3 stents inserted in my RCA Dec 2010. My cardiologist put me on Lisinopril (2.5mg) Toprol XL, Plavix and Lipitor. I took all of them for 6 weeks and felt terrible. I was having severe pain between my shoulder blades and chest pain/tightness. The cardiologist said my heart was okay. I saw my PCM and he upped my Lisinopril dosage to 10 mg and I felt worse. After finding this forum I stopped all the meds but the Plavix and within 3 days I felt 100% better. Did a followup with the cardiologist and told him I had quit them all and he said he didn't mind eliminating the Lisinopril but to keep taking the Toprol XL. It's been a week now and the past three days I have been pretty much pain free. My BP has been all over the place but for the most part has been phase 1. I read another blog that I shouldn't have went "cold turkey" with the Toprol XL, but the BP seems to be leveling out after about 5 days of re-starting it.
