I Have Elevated Liver Enzymes, I Have Had A Sore

I have elevated liver enzymes, I have had a sore throat for 2 months and it hurts to swallow. I took amoxicillin for an ear infection during that time, and was tested for strep- negative and no change. I also have started getting headaches which I have never experienced before and I am also dealing with an extreme level of fatigue, falling asleep and no waking up for 17 or 18 hours even when I set an alarm! I'm exhausted, I feel terrible and I'm frustrated because so far nothing has helped. I have an appt with a new pcp in a few days but I want to be able to suggest some testing I can ask for. Any ideas?
