Diagnosed Hepatosplenomegaly, Elevated ESR, CRP Levels, Fatigue, Nausea, Stomach Bloated, Weight Gained. Treatment?

I have been diagnosed as having hepatosplenomegaly, with elevated ESR and CRP levels. I'm extremely fatigued, nauseous, my stomach is bloated, I've gained significant weight without a change in my diet or activity levels of late, have flu-like body aches, mild peripheral neuropathy, have difficulty holding onto a thought, completing a thought and generally feel like I'm in a fog all the time and don't feel well at all. I'm scheduled to see a rheumatologist in a couple of weeks. Any thoughts on this?
