hi gamma and welcome,
we have other spouses/mates who are members here as they search for answers about how to help their partner. Your husband is lucky to have you on his team.
Most of us are on plaquenil...it is the most common treatment for lupus, but it can take up to 6 months to work. I am surprised that your husband has not been to a rheumatologist....this is the dr. that specializes in lupus, and you should find a good one in your area.
feel free to ask any questions, there are some incredibly knowledgeable people here. Also, if you will look in the "stickys" in the lupus symptoms section, you will find a great deal of information. Oluwa has a sticky entitled something like 101 home treatments (not accurate, but close enough for you to find).
I do know that your husband needs to protect himself from the sun and other uv rays. requires wearing clothing that covers the body, wearing a hat and sun glasses, and using high spf sun block. the sun and hot showers can aggravate the skin rash.
again, so glad you joined, and i look forward to sharing informtion with you.
