when i woke up in the recovery room, i asked the nurse how long did it take them to finish the test, she said 14 mins, but i heard others say like 20-30 mins sth, and i didnt feel anything during the procedure, i guess i was out, and i don't feel anything uncomfortable after, so do you think this is normal? i feel like i didnt even do the test! and the doc said i only have a hemorrhoid. should i believe him?
