Is colonoscopy a simple procedure that can be performed well by a junior doctor?

Hi Cai Shum, A colonoscopy is one of the investigative tools we have to examine the colon, rectum and in some cases the terminal ileum. The alternatives are a computed tomography scan of the colon (also known as a CT Colonography) and a barium enema. The key benefit of performing a colonoscopy is the ability to directly visualize the colonic lumen through a high definition lens and biopsy the lesion if necessary. This cannot be done with the other imaging options.

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.
