I’m a 15 year old female. I’ve have this lump at the top of my tail bone, but it’s on the left side of my buttcrack (TMI), i believe it “developed” after I was straining on the toliet because my stool was hard and kind of hurt. It’s been there for about 2-3 days and even caused me to have a high temperature. I told my mom about it when she noticed I would lean over whenever i walked. The only thing that was able to ease the pain was for me to take hot/warm showers, and let the heat soothe the pain in a way. but it’s been about 5 days and the pain is still there but just not as aggressive. I tried looking it up and all i keep seeing was CYST and the immediately sent me into a panicked mindset. then today i found this site and am now thinking it’s “Coccyx”, but i probably will need some more knowledge of that. But if anyone can help me know what it actually is, please let me know.
