Hello, Thanks for your query. Pain occuring around the tail bone area (coccyx) is termed as coccydynia. Coccydynia is felt as a localized pain and will generally feel worse when sitting or with any activity that puts pressure on the bottom area of the spine. There are numerous causes for coccydynia. An xray of the involved part (sacrum with coccyx) and an MRI scan will help in identifying the culprit. The general treatment guidelines for this condition includes the following - * Sit completely upright with proper posture — keeping back firmly against the chair, knees level with hips, feet flat on the floor and shoulders relaxed * Sitz baths (which involves soaking hips and buttocks in warm water), which helps in providing pain relief * Lean forward while sitting down * Sit on a doughnut-shaped pillow or wedge (V-shaped) cushion * Apply heat or ice to the affected area *Physical therapy involving strengthening of pelvic area muscles , stimulation with ultrasound therapy I do hope that you have found something helpful and I will be glad to answer any further query. Take care
