They affect everything from your nervous system and brain to your thyroid gland and shoulders. If you're experiencing headaches, neck pain, or anything else in this general area, your cervical spine may require treatment
Your upper and middle back is known as the thoracic spine. This section of your spine has 12 vertebrae, ranging from T1 – T12. Your stability is due to your thoracic spine. Your thoracic spine affects the center of your body ranging from your arms and esophagus down to your small intestines. Common effects include stomach troubles, gastritis, digestive problems, and more.
