I am fasting some days each week to get rid of hip bursitis at present.
I seem to be dogged by strain injuries having had a few in my life and now I have bursitis. I helped a friend grind a floor for a few hours and I was not used to the kneeling which caused my bursitis which is an inflamed gland on the side of the hip.
If you want to know how I am curing myself with urine then read on.
At first I took more than a cup of urine during the day and it seemed not to do anything. It happened before Christmas and I have had many jobs to do since plus a holiday which has kept it inflamed. The standard cure is anti inflamatories (which I will not take), icing and rest. I tried a fast (drinking all of my urine and no food) of 3 days before holidays and it worked for three days. Three weeks after that I fasted for 3 days and it was great which lasted again for another three days, next week two days which was good, then another two days the following week which to my surprise did nothing and today is the third day of this week.
It is very painful and all pain goes away after two days of fasting on urine. I have too many things to do to just stop and fast until it is healed. So my routine is 3 days fasting, 4 days food.

does it help in constipation?
