The L5-S1 junction, located between the lumbar curve (which sweeps forward) to the sacral curve (which opposes the direction of the lumbar curve and goes backward) is particularly vulnerable to misalignment, wear and tear, and injury.
While some spinal tumors have no symptoms, most eventually lead to back pain and could also cause neurological deficits, such as numbness or weakness. Spinal tumor symptoms can vary greatly based on where the tumor is located and whether or not it is cancerous.
Neck pain has many potential causes ranging from acute problems, like muscle strains and whiplash, to conditions that develop over time, such as cervical spondylosis (neck osteoarthritis) and myofascial pain syndrome.
