a mass or something in my bum

I went to the butt doctor today to see if he could see/ feel anything near my tailbone that's giving me this aweful pain ...and he did feel something that concerned him. heaid it dosent feel like cancer but wants me to have a MRI. and colonoscopy ..I will be getting the coloniscopy on the 31st of may and the nurse is going to be calling me to let me know when my MRI Ais scheduled...I am a bit scared but at the point that I just want a answer for whatever this is that is hurting me so much :-(....my xray of my coccyx didn't show anything ...I wanted to fill you in on things ..thanks so much

I did ask him if it could be a cyst and that's what the MRI will look for ...us great minds think alike lol......after my nissen surgery the woman in the next bed farthest from the bathroom was doing a prep for her colonoscopy ..I felt so bad for her pooping up a storm with as her adiance pooroman ...I am keeping positive and hopefull it will be somethingcthat will expain this pain I have and hopfully a way to fix it
