Your Symptoms
You don’t need any more reason to be worried, so you should probably avoid Googling any symptoms or ailments you might have. You’ll just be led down an unnecessary hole of paranoia and unneeded stress. Additionally, if you search for certain conditions, you may just run across some gross images you can’t unsee.
But more than that, the whole “WebMD cancer” meme is a meme for a reason. Do yourself a favor and leave the diagnosis to medical professionals. If you’re not feeling well or there’s something you’re concerned about, you should go see a doctor instead of Google. You’ll sleep better and feel better because of it.
