Spinal decompression is a non-surgical treatment approach for relieving back and neck pain caused by compressed discs and spinal nerve impingement. It involves gently stretching the spine to create negative pressure, which helps alleviate pressure on the discs and promote the retraction of bulging or herniated discs. This therapy can improve nutrient and oxygen flow to the affected area, promote healing, and reduce pain and inflammation. Spinal decompression is typically performed using specialized equipment and may be combined with other therapies like manual therapy and exercise for optimal results.
