Hi cak, welcome to the forum!
The only suggestion I could make would be...see if your doctor is willing to run an ANA 8 ELISA profile. That would show if your body is making specific antibodies for any of the connective tissue diseases.
ANA can change, so many times it is a wait and see game. Both bloodwork and clinical symptoms are important. I would recommend taking pictures of any swelling or rashes you may get....lot of times these things will disapear before you have a doc appointment.
I'm glad you have joined us...there are many caring people here who do understand and can help.
Please take some time to lok over fibro 101 on the top of the page, Sherrine has put together some wonderful info for us,
Keep posting, we do care!
Hugs,Robin
