I was told about 4 years ago (pre-PBC diagnosis) that I had costochondritis. There really isn't a test for this, they just treat you with ibuprofen and if you get better they figure thats it (or that is what I was told) I have been having left side upper chest pain, localized just to the left of my sternum for a long time. Thought it was cardiac related, underwent several ekg's and last Friday had a nuclear cardiac stress test, all normal. My back on that side hurts too. I am in just in so much pain. This all started back again, after the past couple of months of super high stress. Two deaths in the family, cancer diagnosis (me) etc. I know its probably related, but I would really like to know what is causing this. Tylenol takes away the pain somewhat, but I broke down and took some ibuprofen for a day (even though I'm not supposed to with my liver) and it made it much better. I really would like to take more ibuprofen by my liver ached when i took it. So its either suffer the chest and back pain or the liver discomfort knowing I making it flare. Do you know if there is a direct coorelation between PBC and Costochondritis or even Tieze's syndrome, which is the chronic version of this?
