So long story short, I was climbing something when a foot hold beneath me gave way. I fell about 1-2 stories flat on my coccyx and legs and felt horrible pain. It resided slowly as I walked around for the rest of the day, but now, whenever I sit or get up from sitting, there's a little pop along with sharp pain in that one area. Does this need medical attention or should I just tough it out?
It might just be bruised, but with a fall from that height I would head to minor injuries/A&E to get it checked out (you could have other injuries too). In any case the treatment will be the same - painkillers and avoiding sitting on hard surfaces until the pain goes away in a few weeks' time (a friend of mine cracked her coccyx and had a ring-shaped cushion to sit on until it healed).
best you go to the emergency room or urgent care to get it checked out. good luck
