Hi I wonder if anyone can let me know anything about taking anti inflammatories and the affects it may or may not have to someone with pbc. I have been prescribed Naproxen for a suspected strained muscle the pain is my righthand side ribs - the pain was so painful I couldn't move. I had my blood tested and have a slightly raised esr result. I have been given a two week supply and am just a bit weary of the affect on my liver - my gp isn't. Any comments are very much appreciated. Thanks.
