I've been to the doctors maybe 4 times in the last 20 years, everytime I go I wait for more than an hour even tho I have an appointment..go in the office and he's telling me stuff I already know, and to rest up and take flu medicine. When I went to see a chiropractor about my knee pain when I crashed my motorcycle, same thing...rest it and ice the swelling....
Ill go to the ER if I have a limb dangling from its socket but other than that, Wikipedia and car forums will be just fine.
