I don't think I would stop due to bursitis. It is possible you built up your UT too quickly. It is important to start slow.
A good way to start is to start with a homeopathic solution putting 2 drops under the tongue twice a daily and build to 10 drops 2-4 times a day.
One can also put a couple of drops of urine under the tongue each time you urinate.
The after you have done these two, a great way to do UT is to use an enema bulb, and do urine or aged urine by enema. This will get the urine right into the liver to cleanse and get the nutrients into the blood stream.
Then begin with 1-2 ounzes of urine twice daily. I have heard that about 2-3 in the afternoon the body gets rid of more zinc and selenium, so if you do two times, do it first morning urine and early afternoon. I have also heard persons who drink 1-2 ounzes each time they urinate.
I personally inject the urine every other day 0.5-1.0 ml. This has great results and particularly if you do some aged urine and some regular urine.
I recommend the book the Golden fountain that tells the benefits of all the different application.
