<s>[INST] Hi doctor, My 11 year old daughter, who weighs 35 kg and is 4.10 feet tall, is suffering from pain in the tailbone. The x-ray revealed that it is a congenital elongated tailbone. The report read, coccyx shows longitudinal clefting, which appears to be congenital variation. She has been advised to sit on soft surfaces, with a pillow, since sitting on hard surfaces seems to aggravate the pain. She has to be careful about her sitting posture all the time since sitting in the wrong posture triggers the pain. I needed to know if this pain will reduce with age since she is a growing child? Or can it further increase and cause problems later? Also, can any exercise or surgery solve the problem? [/INST] Hello. I wish you had included the x-ray with the detailed description. For more information consult an orthopaedician and traumatologist online --> </s>
