42, 5'5" 150 Had severe pains under my left rib last week. ER took CT and said it was Pleurisy, although I have not been sick or been coughing. Later in the week found out there was an incidental finding of a cyst on my liver. Had an US on my liver and found a large complex cyst on the left lobe. Was asked to have another CT of the liver. I have trouble breathing due to the pain, and the pressure it is causing is quite uncomfortable. I was told that I had to have blood work done first, and to wait 3 or 4 days. No one seems to really have a clue what to tell me to do. I've been miserable for a week and just want to go in the right direction.
