chest pain with slight swelling on left side around rib cage

Some gastrointestinal disorders may present as atypical chest pain. This chest pain may not be related to the heart. Can be associated with gastroesophageal reflux (reflux of stomach acids) and esophageal spasm. In addition, chest pain can be caused when food or liquid gets stuck in the esophagus. Food may get stuck for many different reasons, the most common being stricture or narrowing in the bottom of the esophagus.

It's best to check with a doctor for a correct diagnosis.

This also can be costol chondritis...(spelling might be off)... which is the inflamation of the cartelage of your rib cage.  It can cause intense pain that radiates up the left side and can mimic a heart attack but the pain changes with intake and exhale of breath (as your rib cage expands).  Anti inflammatory meds make a huge diffrence.  I was diagnosed with the chronic version of this called Tietze Syndrome when I was 15.

I have fibromyalgia and have also had Costochondritis in the past, but now I have swelling of the entire upper left rib cage, and an x-ray revealed something solid in that same area. I have fibrocystic breats, and knowing the difference helps minimize the concern. Costochondritis is VERY painful, and since I've had it a long time perhaps it has become chronic - the Tietze Syndrome. Thanks for the information. I will persue the issue.
