I have a sharp pain at the top of my butt crack.. It is excruciating when touched and hurts when sitting or lying down on my back. There no is bump to be seen. The pain feels like a large stabbing sensation. I can feel a little swelling on the right side.
Hi and welcome to Chat Doctor. The pain you are feeling in your butt crack can be due to a condition called, Coccydynia, (tailbone pain or coccyx pain), generally feel worse when sitting or with any activity that puts pressure on the bottom area of the spine. 1. To treat this, do Chat Doctor.  2. Use a tube or a soft cushion while sitting on a chair.3. Take an ultrasound therapy from your nearest PT center. The pain if not chronic should take 2-3 weeks to disappear. I hope this information is helpful to you. Take care and have a nice day
