4. Weakness or numbness in one side of your body
If blood flow is restricted or cut off in your carotid arteries, it could cause you to experience weakness or numbness on one side of your body. The carotid arteries are those that carry blood from the heart to the head and are located on either side of the neck. They both split into two branches, one that carries blood to the brain and eyes and the other that takes it to the face, tongue, and outside parts of the head.
