There is at least one drug (Cenicriviroc) in development for this disorder, and it has Phase IIb underway, presumably based on Phase I/IIa results which looked pretty good. Perhaps you could get hooked up with a liver specialist in Chicago:

Here is a description of the ongoing clinical trial:

Here are the results of the animal model study:

Antifibrotic Effects of the Dual CCR2/CCR5 Antagonist Cenicriviroc in Animal Models of Liver and Kidney Fibrosis."

CONCLUSIONS:
CVC displayed potent anti-inflammatory and antifibrotic activity in a range of animal fibrosis models, supporting human testing for fibrotic diseases. Further experimental studies are needed to clarify the underlying mechanisms of CVC's antifibrotic effects. A Phase 2b study in adults with NASH and liver fibrosis is fully enrolled (CENTAUR Study 652-2-203;
NCT02217475)."

Pain management is something else entirely - I'd think MM would be the best approach.
