I want to ask about the hard lump in my tailbone. 3 years ago I had a soft bump on it and I took some antibiotic. I couldn't walk for 1 week because of that. There's some fluid in it. And eventually, it became okay. But later these years I felt pain again in my tailbone but now its not a soft bump. I have a hard lump on it. Im worried about it. I read about cyst and cancer in tailbone. I hope you have an answer about this. Thanks.
