I've read an article about health benefits of infrared saunas, Is it all true?

My older brother will be 40 this year is draining my retired father to the point where he may soon not be able to support himself.  My brother ma be bi-polaro depressed and cannot seem to support himself.  My father cannot seem to cut him off.  What can I, or should I do.  I know that when my father pases on that I will have to cut my brother off. 

I really need suggestions.

My stomach is killing me, and I got liquids coming out both ends. Can I take Imodium AD, and Pepto Bizmol together?

Why are my nuts so big?

My hands shake. It's chronic. And sometimes a random lone muscle contracts and twitches by itself. It started several years ago. I'm twenty. No, I'm not drunk, drugged or whatever. I havent been beating orphans or kicking puppies either. I can't afford a doctor. Whate are the possible causes? How to cure this?

anybody?
