I learnt long ago that THE INTERNET IS THE BEST DOCTOR IN TOWN..

With it, you can research your ailments, join forums for fellow sufferes to compare notes, look up treatments and medications etc, then you can visit your doctor knowing more about it than he does, and keep tabs on him to make sure he's giving you the right treatment and right meds, haha.
PS- One guy said that he told his doctor that he'd researched his condition on the net, but the doctor wasn't too pleased, so it's best to not let on to the quacks..
