For what it's worth I had a fever for about 9 months, it never spiked over 103, but it made living life a terrible inconvenience. I had every test although they did not put me with an infectious disease specialist. I had cervical and uteran cancer but did not need chemo or radiation after the hysterectomy. Ended up with an extended hospital stay (more than a week) where they discovered an abcess 6 weeks after my surgery? Now, I know that they probably had your wife on lots and lots of antibiotics but they tried several with me as well....it finally helped!!! But then all of the other symptoms started getting worse....Numbness in legs, hands, difficulty swallowing, dizziness etc. finally ended up fainting so much that I was not 'all there' and required another hospital stay. Also, my symptoms did and do seem to get worse when I am/was hungry or when GI issues flared up. Do not know if this helps but I wanted you both to know that at least it gets better. It has been 3 years and was finally diagnosed in Jan of this year. Now with the meds., fluid loading and vitamin intake I seem to be handling things a wee bit better. With that said it has been a long road. I might add that I believe this is something I have had all my life. It was just exasperated by the Cancer/abcess etc. Thank God you are such a wonderful person and I think via all these posts you understand how helpful that can be!!! Best of everything, prayers and love to all of you!!! Take care and please keep us updated, Michelle
