Hello! Welcome on HCM! I carefully read your question and understand your concern. I would explain that her symptoms seem to be related to a viral infection. Her back pain could be related to myalgia, which is a common complication of flu infection. Has she taken acetaminophen during these days? It can lead to transitory elevation of liver enzymes. I recommend to take some rest and painkillers like ibuprofen or naproxen for the pain. If the problem persists, I would recommend consulting with a gastroenterologist and perform further tests to examine her liver function. Hope you will find this answer helpful! Best wishes, Dr. Aida
