Will colonics rid me of my fecal odor?

Hi everyone. I am 20 years old and I have been having problems with a fecal odor since I was about 15. I have chronic constipation, bloating, constant gas, and hemorrhoids along with the fecal odor. I think the odor has something to do with not having healthy bowel movements because that is when the smell started. When I started having incomplete evacuation I noticed that I would have a hot feeling coming from just inside my colon. I always have that hot feeling there but it gets more hot when I pass a BM. That hot feeling being there is an indication to me that the smell is there because before that feeling started I did not have an odor. Someone on one of the other forums had my symptoms and was cured by drinking a mix of whole flaxseeds and fruit. It made their BM come out all together and perfect all the way to the tip. When I tried it, it made me have a BM but it was not formed all the way to the tip and I still have IE and the warmth inside my colon. I am wondering if maybe I need to get a series of colonics and then try the flaxseeds because those seem to work for multiple people. Maybe the reason it is not fully working for me is because I need to get the junk out of my body first that is preventing me from having a healthy BM. If anyone has any ideas on that it would be very appreciated. My main focus is just getting rid of the fecal odor. I used to not have it so I just have to figure out a way to get back to where I used to be. Thanks.
