I too have AIH but have not had the inflamation you have described. I have had severe muscle cramps particularly in my legs but no swelling. Has any of your medications recently been reduced? My pred recently was dropped from 10mgs to 5mgs and I experienced bad headaches, mood swings, and the famililar exhaustion. I know that withdrawls from some meds can cause real problems, but I have not heard of those symptoms being associated with a result of this disease. Let me know what you find out and keep us posted.
