Autoimmune disorders generally travel in packs...unfortunately. So having one predisposes you to acquiring others. Most people end up having 2 or more. I have AIH only at the moment. I too have liver pain. They can't sort it out so it's just something you get used to. It isn't too bad, just a sharp stabbing thing occasionally and pressure other times. I am in remission and only on Imuran.
Did they say why they took you off the Humira? Is it more toxic to the liver than other remedies? Don't randomly take any pain relief without first speaking with your hepatologist. You are seeing a hepatologist for your AIH, correct? If not, you should ask for a refferal to one. Don't drink alcohol anymore either. Before taking any OTC it is best to check with your hepatologist as well.
As per the "primative" AIH treatments...steroids are used initally to reduce the inflammation caused by the body attacking the liver. Then immunosuppressants are added as steroid-sparing agents and to suppress the immune system to avoid future attacks/flares. It is a rare disease so it doesn't have the research backing that RA, MS, Crohn's and other more popular diseases have. So they work with what they have and that is to treat us similarly to transplant patients as the end result is the same. Some AIH'ers of late who have issues with the pred have been introduced to Entocort (Budesonide)...you could always speak to your doc about that one.
Hope that helps a bit,
