Back spasms can be the result of injuries to the muscles, tendons, and ligaments in the back, or they can be related to more serious medical conditions. In addition to heavy lifting, any activity that puts excessive strain on the muscles and ligaments in the lower back can cause an injury. Acupuncture relieves lower back pain and restores range of motion. Independent research teams find acupuncture effective for treating lumbar disc herniations, lower back muscle spasms and sprains, and chronic pain of the lower back. While OTC or prescription pain medications may offer some relief, they mask the pain to the point that a person continues to do a certain activity that may worsen their physical situation.
