25M High SGPT/ALT 180

Hi. its my first time to post. Last week, I was rushed to Emergency Room as I observed rashed on my legs. It is not itchy at all but very alarming because red dots are covering my legs to feet. I dont drink alcoholic beverages, but I am 280 lbs. I took tests and got my results back. Everything is good except SGPT reaching 180 units. I will be going back to my doctor with results, 4 days from now. Any advice you can give me?
