I have Autoimmune Hep, with stage 4 chirosis. Last month I also had pleurisy.
It started with a trip to the ER cause I could not breathe, they diagnosed bronchitis gave me tons of meds (cause I am on immune suppresents) and did an xray. The Dr looked at the xray and said I was fine. Two hours later he calls me on my cell phone and says the radiologist saw a "nodule" on my lung and to contact my primary Dr. and get a ct scan.
3 days later I went to my primary cause I thought I was having a heart attack. He checked me out and said it was pluerisy and that it is common to mistake it for a heart attack.
I had the Ct scan and it was ok.
He said the pain is known as the "devils grip" and it certainly was. When the pain would start it was unbearable the only thing I could do was lay down and not move.
The only thing that helped was taking advil (which I am very limited to taking) and I tied a shirt around my chest as tight as I could which sort of held my lungs tighter (if that makes any sense at all) I read some where on the interenet that it would help.
The bottom line is I had it for a month, and it will eventually go away but it is horrible.
I would rather have a root canal with no novacaine than have pain from the pleurisy.
I did read on the Mayo clinic web site that it could be liver related/ autoimmune Hep.
I hope some of this helps.
