What Is a Muscle Spasm?
Pain from injury, whether it is sudden (acute) or continuous (chronic) can sometimes be caused by muscle spasms.3 That’s because after an injury, such as a strain, muscles may painfully contract, resulting in a spasm.9
Muscle spasms can occur in many parts of your body. One of the most likely instances is when you strain a muscle or ligament in your back. This occurs when the muscle is taken beyond its normal range of motion.3,9
A muscle spasm causes back pain through rapid nerve impulses. The pain is your body’s way of keeping that area from being moved, because further movement could cause more damage.9
What You Need to Know About Your Treatment Options
Treatment for the type of acute and chronic pain associated with muscle spasms includes physical therapy, applying cold and heat to the affected area, and other proven methods like exercise. Your healthcare professional is the best source of information about your treatment options, but when it comes to muscle spasms, staying active is often the best thing to do.3,4,9
