Misalignments of spinal vertebrae, disc herniations, degenerative discs, spinal muscle spasms, and calcification of the vertebrae can put pressure on the nerves as they exit the spine. Space occupying lesions like tumors, bone spurs, cysts, etc. can put pressure on nerves, but fortunately, this is an infrequent cause. The Tru-Align tractions and realigns the spinal vertebrae, thus improving disc problems, opens up the space where the nerves exit, and stretches and relaxes spinal muscles.
