Can Colonoscopy Detect Broken Tailbone?

I fell down while rollerblading 3 months ago and I am still having problems sitting down. I believe I broke my tailbone. I am 41 yrs old, 171 lbs My dr took an mri of my back 2 days after and said it was nothing but the pain is still there. I'm going for a colonoscopy on friday, would they be able to tell if my tailbone is broken
