angina
"I was prescribed Renexa to increase blood flow in preparation for a heart cath. Heart cath showed no heart disease. 
Upon taking Renexa, by the 2nd day I  observed that my Fibromyalgia pain was completely gone! My cardiologist said they have seen cases where it has helped with fibromyalgia. He said I absolutely could continue with Renexa for fibromyalgia. I have not taken a single pain pill since!"
