myocardial bridging

I was diagnoised with Myocardial Bridging 4 years ago. Since then it has caused me to have severe chest pains which put me in the hospital several times. Each time they run an EKG and it shows nothing. The Dr. has me on Isosorbide monatrate. I also take Caduet for blood pressure and high colesteral. The cardiologist says my tests aren't getting worse but I know my chest pains are getting worse. So I have two questions, first I would like to know if anyone else has symtoms (symptoms) that get worse? and second the drs. are trying to get me on SSI Dissability. Has anyone else been given dissability because they just cant work. Every day my chest hurts so if anyone could answer these questions for me I would be so grateful. Usually when I o to a new Dr. or hospital they dont seem to have ever heard of Myocardial Bridging.        Thanks for reading my questions   Tammy
