Suggest Remedy To Relieve Pain Due To Cyst In Liver

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.
