Ok... Omg... So Embarrassed. I Had My First Colonoscopy On

Ok... Omg... so embarrassed. I had my first colonoscopy on Jan 7th. Everything went well, then this last Wed/Thurs. 20th, I started to feel something strange down there in my rectum (anul) it didn't hurt, just felt strange. Yesterday (Sat.) 23rd, felt down there in the shower... swollen, round... didn't push too hard. But I noticed it when I walked all day yesterday. Bowel movements don't hurt. I'm freaking out somewhat. 53 yr old female. I do have a call into the doctor that performed colonoscopy... called yesterday....
