Spinal stenosis is a narrowing of the spine, often resulting from degenerative diseases, such as osteoarthritis. As the spinal vertebrae and their protective discs wear down, they can put pressure on the spinal cord and nerves. Pressure on the nerves can also result as the ligaments in your back thicken as you age, or if you have herniated discs due to injury or disease.
CRPS is a chronic pain disorder that typically affects one limb. There are two types of CRPS. CRPS-I is caused by an injury like a sprain or fracture. CRPS-II develops due to nerve damage. Their characteristic symptom is that the initial pain persists long after the injury or nerve damage heals. Additionally, the chronic pain is disproportionate to the original injury.
