The patient is often asleep throughout the procedure due to the sedation administered so essentially the patient often has no recollection of the entire procedure.

If a patient chooses to undergo the procedure without sedation, the common sensation will be that of abdominal cramps and bloating due to the air pumped into the colon during the procedure. This can be very uncomfortable.

Which will give the best results between a standard colonoscopy, a virtual colonoscopy and a capsule endoscopy?

To find out more about getting a colonscopy in Singapore, you can read my Complete Guide To Colonoscopies In Singapore (2018). A standard colonoscopy’s sensitivity is in the range of 95 – 98% accurate, while a CT Colonography’s sensitivity can range from 90 – 95%. However, it is imperative to note that the sensitivity and accuracy of either investigation is highly dependent on the quality of the bowel preparation before the procedure. The poorer the bowel preparation, the lower the accuracy.

Do I need a colonoscopy for tailbone and anal pain to rule out cancer?

Hi, The description of your symptoms appear to be proctalgia ani. While it literally translate to "pain in your anus", the persistence of your symptoms warrants a physical examination by a doctor. The causes can range anywhere from an anal fissure (tear in your anus), to deep anal infections, to referred pain from somewhere else e. g. coccydynia / pelvic floor strain (from your weight lifting), and stress.
