No one is using arthritis cream and right now it is not so strong. We are in the middle of some home repairs as we just bought a house that needs work. I was wondering if it was something dangerous in the home or --I know this sounds crazy--but maybe something of the paranormal.
Garlic is known to scare off bad spirits, so that would be a good thing if it were paranormal!
That being said, perhaps you pulled out something from under a cupboard, or broke open a wall before the smell occurred? It is possible that who ever lived there before planted garlic as a new home ritual. Or, there could be some old garlic stuffed in a cupboard somewhere. Someone could have even spilled garlic juice at one point in time.
I have done some research and nothing caustic would be causing your odors. So that's a good thing too!
Hope you enjoy your new home.
