Hi Callaway,
You mention both Bart and Babs, but your symptoms could also be from Lyme. Have you been treated for Lyme or at least been evaluated for Lyme as well? Just trying to cover all bases.
The swelling that moves around your head/neck area, could be swollen lymph nodes - they are all over your body and are particularly concentrated around the head & neck area. You can see them here for the head & neck area:
www.nhlcyberfamily.org/nodes.htm They are the yellow things in this picture.
Are you taking anything to help clear the lymph nodes? What about
your detoxing routines? Particularly anything that might be helping the lymph nodes/system like lymph massages?
It definitely sounds like you have more than Babesia going on though.
