How do you treat upper back spasms?
Use an ice pack and an over-the-counter pain reliever such as acetaminophen, aspirin, ibuprofen, or naproxen. After the inflammation calms down, a heating pad or pack can help soothe muscles and connective tissue. If you have chronic back pain, sleep on a medium-firm mattress.
Your upper and middle back area is less prone to trouble than your lower back. That’s because it doesn’t bear as much of a load of your body’s weight and work as your lower back does. But this area, which runs from the base of your neck to the bottom of your rib cage, can still be a source of pain.
