Sounds like your doctor is starting with the obvious. Your feet swell up... may be inflammatory since you have Hashimoto's.
Just to compare... I have had elevated ESR forever...never positive for RF, or ANA. But I have had two episodes of drug induced lupus (which often does not elevate ANA).
So people are different in how they present with problems of pain and swelling.
RF blood work BTW is not very accurate.

Remember testing is only a snapshot in time...The results may change in the future. Visual presentation of observable phenomenon still remains at the heart of all diagnosis.
I'd keep a journal of each day. Finding a trigger to your flares and better days, will always be helpful to you and your doctor.
