Hi Zaddruga - welcome!
There is a wealth of information here on this site - I hope you find it helpful to you as you have several of the symptoms, but no diagnosis.
In my opinion, if your mother had Sjogren's and RA - it is a good possibility that you too would have it. We have several members here whose mother had Sjogren's and they do too.
Do the doctors say you don't have dry eyes or do you just feel you don't have the dry eyes? Some times we become so use to things that we don't realize how dry we are and just accept it as allergy eyes, wind, sun, etc. The eye drops are so soothing to the eyes.
Sjogren's can do a real number to our teeth. It was my dentist office that suggested I get tested for Sjogren's as their instruments were sticking to my cheek and teeth during an exam. I never leave the house without a bottle of water with me. I have to have some sort of liquid to help wash food down - breads are really tough to get down without it.
Many times, doctors look at individual symptoms and not the whole picture - which is why some members take years to get an official diagnosis. You have to be your own health advocate. Keep pursuing it until you find a doctor who will listen to you and treat you for your symptoms.
Your Rheumy should know that autoimmune diseases like to bring their friends (

) - and given your family history, should be keeping an eye on your symptoms, etc.
