Dyan suggested that if you're sore after class, be "easy" on your seat. "Keep the area cool and dry and choose comfortable surfaces to sit on after," she said. From a physical therapy perspective, Karen said that soreness in the perineal or vulvar area discussed before could be due to an irritation of the pudendal nerve. "This can cause pain and burning when sitting and may be relieved by laying down." So take it easy!
