No, Echoes, that's part of the problem; if you don't have the physical symptoms that take you to the doctor or you ignore them until they "go away", they can progress and you can end up with psychiatric symptoms:

I don't live/play in wooded areas and usually ticks stay on one for awhile (going walking in the woods, for example, it will take the tick quite awhile before it's full and drops off you; one is supposed to check one's self/children/pets, etc. after being outdoors in a tick environment) and have not had any physical symptoms like those that go with being bitten in the last 7 years I've lived here, so do not feel the need to be checked :
