I would first like to say that I am so sorry that you two are suffering with this BO problem, it is truly sad and breaks my heart reading these; no one should have to deal with that. Until recently I found out about this conodition when I joined this site for weight loss. I am not suffering from BO but I would like to suggest something that may help.
desperate jason, you mentioned that you feel like something is stuck in your 'bum' that is causing the smell to increase. I don't know but I asked a friend of mine who is a nurse and she told me about a procedure called colon hydrotherapy or colonic irrigation, which is the use of substances added or mixed with water in order to detoxify the body. You may want to look it up and find an experienced, certified person to do this for you, that is if you do not want to go to the doctor or have been and still no help. It may be worth giving this a try. Here is a youtube video i found for you to give you an idea of the procedure, you can see lumps of feces coming out of this man's body from the clear tube. I wish you both the best of luck. Sorry I could not be a better help.Keep your head up.
