In actuality there are a lot of muscles, tendons, ligaments, and so forth that keep it all together… and one little muscle that connects your tailbone (sacrum) to your hip bone (proximal humerus) can cause a lot of problems. That’s because the largest nerve in your body, the sciatic nerve, runs right through it. When the sciatic nerve is compressed by the piriformis muscle either because of inflammation OR because you are sitting your wallet… the nerve is unable to communicate effectively with the rest of your leg. This can cause leg pain, tingling and numbness. Continued abuse of the piriformis muscle can cause chronic pain. There are stretches and massage techniques that can be used to help with this type of chronic pain… but the best place to start??? Stop sitting on your wallet!
