I am 26 yrs old and have been dealing with this for over a year and 1/2. I have been to 3 cardiologists who have confirmed that is not related to my heart. 3 card. and 5 other docs i have seen stated that it could be costochonditis but should have cleared after 6 months by being on roids and anti-inflammation meds. I have had EKGs, xrays, MRIs and stress tests, blood tests, urine tests all have come back negative. I have been through physical therapy as well. I am just 40 lbs overweight is what i am told each time. I have changed my eating habits, excercise by walking more.I am currently taking lyrica, robaxin, savella still feel pain and sometimes have really bad flares up that will take everything out of me.I am at a lost and the pain is taking over my life. I am miserable
