A month ago I noticed an unexpected pain in my coccyx after sitting for a long period of time. I didn't think much of it, but since last week it had got much worse and developed into a dull pain on 24/7 where I can't sit down, accompanied by constipation. I've been to GP who said take ibroprophen and buy a doughnut cushion. I'm very worried as I have not fallen on it, so it's not an injury. GP checked my anus for lumps but there were non. Not sure where to go from here, I'm worried it will never go as there must be something wrong. Anyone else had this out of the blue?
