In the age of Google, it's all too easy to go down the internet rabbit hole after a quick search of your symptoms. Usually, there’s nothing to worry about: That swollen lymph node is just a sore throat, and the rash on your neck is simply irritation from a new lotion you bought. But sometimes a small problem can be a signal of something bigger, so if your gut it telling you something isn't right or these symptoms have recurred, you might want to double-check with your doctor - just in case.
