Hello, just before Thanksgiving, I came down with a fever that lasted 5 days. On the 5th day, I developed a very bad headache/migraine that lasted 3 days. During the fever I went to the doc, who tested me for strep, which came back negative. She said if I had the flu, I’d be better in a few days. Fast-forward to the 3rd headache day: I went to an urgent care place that drew my blood. They discovered high liver enzymes: AST=500’s, ALT=600’s, ALP=188, liver function normal. They sent me to the ER to get an ultrasound, which came back normal. Two days later, they draw my blood again: AST=310,ALT=780,ALP=same. The doc refers me to a GI specialist. One week later, they test me again: AST=34, ALT=220, ALP=117. Three weeks later (a couple days ago): AST=95, ALT=183, ALP=67. I never exceeded 2g (worst case estimate) of Tylenol in 24hrs during my fever. They’ve tested me for tons of diseases, all negative: Hep A-E, CMV, Monospot. EBV IgM was negative, but EBV IgG was positive. They docs seem to think I had mono, but they don’t seem convinced, and the IgM test was negative. I’m not a heavy drinker; I rarely exceed 10 drinks a week. I don’t do drugs. I have one prescription I take very rarely for eczema. I don’t know what to do. I feel like the docs are confused, and now they want a liver biopsy. Frankly I am now terrified. Should I do it? Seek a 2nd opinion? I’ve read that exercise can elevate the transaminases; I worked out pretty hard shortly before developing the fever, and was extremely sore; I also ran four miles the days just before my most recent test.
