Ultrasound Showed Cyst In Liver. Feeling Nauseated After Eating Cabbage. What Treatment Should Be Done?

Question: I believe that I may have a cyst in my small intestine in between my stomach and liver. An ultrasound result stated that I had a cyst on my liver. Since January, I have had a re-ocurring cyle of 2 weeks of pressure pain just to my left of my right rib cage by my liver. Next I would have a burning pain for 1 to 2 weeks with an accompanying dead animal smell for 1 to 2 days after what would appear to me to be a cyst bursting. About 1 month ago, I took an anti-biotic for my sinuses and my pain began going away for the abdomen as well. About 2 weeks ago, I ate a cabbage dish and felt like I poisoned myself. I felt severely nauseated, achey all over, and a liitle weak. I ate as little as possible, mostly drinking frozen mango juice and soft food. The pain then felt like a bag of dull razor blades was in that location where the alleged cyst is. I have begun eating more different and solid food now. I have been eating mashed potatoes as mashed potatoes seems to pull out food that have been stuck in the lining my digestive system before. I seem to feel somewhat better, but not completely. What can I do to clean out the cyst and heal the cyst? Will I be able to do this without medical treatment? If not, what is the medical treatment for this type of condition?

I have many blood results and the ultrasound result. I will have to scan them and then upload them for you. I don't remember anything being too detailed. Just the size and general location of the cyst. I don't think the report is going to be very helpful, but I will send the results that I have. The mayo clinic is who performed the ultrasound. I may be able to request more information from the test from Mayo? Would they have the actual ultrasound and would that actually help?
