I just had a colonoscopy. Now I have what looks like rope burns on my belly near my groin. What happened?

I texted my doctor (he gave me his cell number) with the news. I have photos, but my cell won’t send the images. Anyway, of course he’s not responding. This is not an emergency, but the wounds are oozy, and I can find no reference to this sort of thing associated with a colonoscopy.
