A few days ago I was experiencing some abdominal pain thinking it may have been bad gas, or something bad I ate it wasn't given much thought. When it wasn't getting any better I looked up my symptoms on the "Symptom Checker" on WebMD. Within just a few clicks of the symptoms I was experiencing at the time it said to seek medical attention right away! Then I drove myself to the local ER where I learned that I had appendicitis and had to have my appendix removed if I had not it would have been too late.
Thanks, WebMD
