Hi, Jana. There seem to be so many chest-area pains with lupus, it's hard to know. It's an area that can have inflammation in a variety of places (lucky us!) I've experienced chest pain darn near constantly for the last 18 months - to one degree or another. Pericarditis and pleurisy were diagnosed, but they didn't feel exactly the same way twice. Sorry - that's not a lot of help. If it continues, you may need to talk to your doctor. I've read that most people with lupus will experience chest pain related to inflammation at some point during their disease, so most doctors who treat people with lupus will have a pretty good idea what's going on. Hope you find some answers!
