One of the most popular and trusted sources you can find medical information online is through WebMD. It's a one-stop medical information site with loads of information.

Their Symptom Checker is just one reason it sits at the top of this list. Fill out basic information like your gender and age, and then use the body map to pick where on your body the symptoms are occurring. From there, you get to see any possible conditions that are causing those symptoms.
