Wrap the ice pack in a towel to protect your skin. Alternate the cold pack with a heating pad on low setting. Don't use a heating pad for longer than 20 minutes at a time. Follow your provider's instructions for doing special stretches. Stretches and exercises can relax and strengthen the piriformis muscle. Use proper posture when sitting, standing, or driving. Sit up straight and don't slump. Your provider may prescribe muscle relaxants. This will relax the muscle so you can exercise and stretch it. Injections of steroid medicines into the area may also help.For more severe pain, your provider may recommend electrotherapy such as TENS. This treatment uses electrical stimulation to reduce pain and stop muscle spasms.As a last resort, your provider may recommend surgery to release the muscle and relieve pressure on the nerve.PreventionTo prevent future pain:Get regular exercise.
