Pain at top of buttock crack when sitting can be incredibly annoying and can limit every day life. In todays work culture, we are sitting more than ever. It has become the new normal to sit for 8+ hours a day. Being immobile combined with incorrect posture is catastrophic on your muscles in the low back and hips. This often results in tightness and chronic pain when left untreated. Fortunately, the muscles causing this pain are treatable right at home.
