I've had all kinds of different smells that were never really there! My family has gotten more than a few giggles over me smelling gas when there is no gas engines or gas cans around (like in the house!) or trying to find the rotten food in the frig, even though I've emptied the entire thing out!!
Lyme and the other tick-borne infections cause all kinds of disturbances in our sensory organs. about
all that can be done -besides riding it out with a sense of humor - is detoxing and more treatment.
Of course if you are smelling things burning, please be sure that nothing is!!! Lymies are terrible with memory issues popping up!! Sure wouldn't want to assume nothing was wrong and not go alookin' ....just in case!
