I have been having problems with my heart pounding (much like when a person feels very scared or startled). My dr. referred me to a cardiologist where I underwent several tests and everything checked out fine. In the meantime I developed severe leg pain and hip pain. I was beginning to think that there was no help and I would always feel bad. Someone I know was experiencing the heart pounding and I realized our only commonality was Singulair. I decided to stop the Singulair (been on it for 2 months) to see what happened. The very next day the pounding had subsided. My leg pain is lessening. All of this has changed within three days. I'm beginning to feel more like my old self. This posting site was of great help to me.
