Welcome to WHL, I am glad you have joined us.
This IS a great group of people, as you will find out soon.
Well your symptoms have Lupus written all over.
BUT, you have to see a doctor, take bloodtests and go from there. There is no sense in speculating and worrying, it may be something else. It could be a virus or something totally different.
Your first move should be an appointment with your family doctor, he will decide what to do next.
Again, welcome .
I may have been dealt a bad hand, but at least I'm still playing with a full deck. ( most of the time anyway).
