14. Toothache
You’ll notice that the nervous system is connected by the same network. The nerves are like the veins on a leaf or the branches of a large tree. If you haven’t seen what the nervous system looks like in real life, this is a great time to do so.
It is possible that the same nerves can connect parts of the human body. This can cause pain to be felt in an unrelated area. You may have a spot in your leg or back that causes you to jump when you poke it. This is an effect of the nervous system.
It’s possible that a toothache can also cause blurred sight due to increased pressure and nerves. If you visit your doctor to fix the problem, it is possible that the blurred vision will be fixed along with the tooth.
