A few years ago when I went to the ER with chest pains. After running tests, it was was determined that my chest pains were not due to a heart problem. The chest pains most likely were caused by costochondritis, which was very painful. After that episode I did some research on costochondritis, and how it was connected to my fibromyalgia syndrome (FMS). Costochondritis causes pain around the rib cage, where it connects to the breastbone. It's considered to be non-cardiac, or musculoskeletal pain. It can be scary thinking that you're having a heart attack. If you're concerned about the chest pain you're having, it's always best to get it checked out immediately. Never take chances with your health. Costochondritis can feel like stabbing or burning, or achy pain, depending on the degree of inflammation of the cartilage between the ribs and breastbone. It is not always related to FMS, but having FMS definitely can make it worse. Since being diagnosed many years ago, I've talked with hundreds of women who have FMS and have experienced this painful condition. Ice and an anti-inflammatory drugs like Motrin or Advil can help with the pain, but be sure to check with your doctor to make sure whatever you choose will not interfere with the meds you are currently taking. Try to rest and relax. Costochondritis can be caused by an injury to the chest, or potentially from a persistent cough.
