Upper Stomach Discomfort With Some Nausea,head Ache, Slightly Elevated Temperature

Upper stomach discomfort with some nausea,head ache, slightly elevated temperature (over 99, but under 100), and resent concern that my liver enzymes elevated to above 100. I am a stage 3 breast cancer Servivor 1 year 2 month from my last chemo therapy treatment. About 4 months ago my medical provider wrote me a prescription dose of Neproxin Sodium. My oncologist checked labwork saw elevated liver enzymes so he stopped the tamoxifen he was treating me with over this past year. After 6 weeks we rechecked my liver enzyme, they went up again (this time over 100). They scheduled a CT scan. During the scan (toward the end) when they say you will feel like you are peeing on yourself I also felt a painful warm sensation along my left side. I was told this was not a normal response. I have seen my medical MD and the plan is to slowly wean from the webutrin and then the Zoloft I'm taking. I can feel when it goes up. I'm in much pain. I feel worried. Are there other questions I should be asking?
