You can test some stretching of the piriformis muscle to relieve pain. It is important to note that you must stay within comfort limits, otherwise you could make your condition worse. Also be sure to warm up before stretching.

3. Take your knee with one hand and ankle with your other hand and slowly toward the shoulder that is aligned with your ankle until you feel a stretch in your buttocks.
4. Hold for 30 seconds to 1 minute and release.
