hello.if she has arthritis
please get her thoroughly investigated including all the basic investigations.liver
problem is a vast entity, one needs to get specific tests to come to specific diagnosis to label it as liver problem.all the treatemnt will depend on the investigation reports as few of the drugs for arthritis are hepatotoxic (liver-toxic).so my sincere advice is get her examined by a physician or a rheumatologist
and get the appropriate investigations done.that wil lead to a conclusion and then the treatment.
hope everything is clear.
all the best.
