Two years ago my doctor pointed out my ALP was low at 33 (but AST normal at 15 and ALT normal at 14. Now exactly two years later my ALP came back even lower at 30, and my AST had jumped up to 74 and ALT to 35. I have had mid & lower back pain for about two years, should I worry? I rarely drink alcohol (more in the past), but I love spicy food and I work out quite often. My mother had gall stones. Any advice?
