Hi crazykitty, flecky + AnnaBananna,
Thanks for your suggestions. I'm sorry I didn't respond sooner. Lupus and Lyme disease were both ruled out. The fever and runs have both gone now thank goodness. Both disappeared on the same day. We never figured out what was happening. The the 'dormant' herpes viruses' idea is interesting. I'll mention it to my Doc.
Funnily enough when the 'Flu' went the RA and Fibro got much worse.
What can I say? I don't think the temp was related to RA. I guess I will never know. Thanks for your help anyway. Neenaa
