If a person is thirsty, one doesn't seek the answer in QiGong. One consumes water.
1. Purchase a one month supply of high dose probiotics.
2. Exclude from your diet white stuff devoid of nutrients (sugar flour).
3. Eat massive amounts of fruit and vegetables.
4. Supplement with a fibre mixture of psyllium, rice bran and oat bran (mix together and take a teaspoon 3 times a day, then I crease to a tablespoon.
5. Lavish the area in question with a pain killing ointment (need a prescription).
6. Gently walk to increase bodily movement
7. Use a hand shower to gently rinse and clean the area after bodily function.
You'll be cured.
You'll wonder why you ever had the problem in the first place.
All the above need calibrating.
