What Causes Psoriatic Arthritis And Excess Sweating Post Liver Resection?

I was diagnosed 5 yrs ago with PSC. I had 46% of my left liver removed. Since then I have developed psoriatic arthritis, hypothyroid and several other autoimmune disorders. One of my most debilitating symptoms is my sweating. Yes, night sweating is an issue, but the sweating I do during the day is unreal. If I do anything like walking, bathing or even have a long conversation (essentially any type of exertion other than complete immobilization), I become drenched in sweat. This sweating can last as long as the activity and 30 mins. past stopping. It has really affected my social activities because it is so embarrassing. I look like I ran a marathon and I can even be cold and chilled, even while sweating. Is this PSC, autoimmune, arthritis, or perhaps something else entirely. Thanks ever so much, Angie
