Correct Kritts.
Somewhere in the region of 50% of Lymies dont remember getting bitten and either didnt get the bulls eye rash (looks like target rings), or they didnt get the rash in a noticable area of skin (say on the back).
My dad got the tick on his chest. He didnt have a rash, but 7 years later has attacks (about 3 a year) which puts him in bed for a week or so.
These include night sweats, painful swollen joints - one at a time (fingers, toes, elbows, shoulder) which travel around his body, usually ending up in a finger or toe when its subsiding. Extreme tiredness and dementia type symptoms.
It totally fits.
He kinda agrees with my research. Need to work on him some.
