Pam,
I am a frequent reader of this wonderful board, but post very infrequently.
I read your post today about the rash and eye problems. I am wondering if you should see a rheumatologist because I had similar symptoms and ended up being diagnosed with a very serious autoimmune disease called polyarteritis nodosa (PAN) vasculitis. The came 3 years after my Stage 3A HER2 cancer diagnosis in 2005. I am fine now, but it was an awful illness - and one, I learned, that is very often overlooked.
It's a long boring story, but I now realize that, in particular, my eye problems were a precursor of vasculitis. I have very dry eyes - often red and needing drops - and two times have gotten this awful thing called scleritis where the sclera (or clear lining over your eyeball) got inflamed. As a result, I got this huge sack of fluid above a bit above and below my bottom eyelid. It looked AWFUL, was painful, and hurt my vision. I took steroidal creme and it cleared it up, but I now know it was a sign of vasculitis.
There are many forms of vasculitis - many types are similar to Lupus - doctors often overlook symptoms like loss of weight, general lethargy, rashes, etc. because they can stem from other things (chemo, general malaise, panic over mets, stress, etc.) Here is a link that explains the various types of vasculitis:

If you scan through them, you will see that several of the types involve skin rashes and eye problems...
Of course, I am no doctor, but I do know the feeling of desperately wanting to get an inkling of what could be causing some symptom. And for sure, none of us want to add another doctor to our list, but if your problems continue, perhaps it might be worth thinking about.
God bless you during this difficult time - I am thinking of you and praying for us all -
Jane
