ohh everyone,as a native Chinese,before I was diagnosed with POIS mounths ago,I have been seeking Chinese medicine solution for two years and tried out Chinese medicine for 2 years(4 doctor's different prescriptions).The only effect of one prescripion is conditioning the cycle of night fall,others didn't work at all...Shenkui do exist in some people mainly with bad(sore or painful)waist, fatigue(they called it lack of energy?精力?),and they can be easily cured by commercial Chinese medicine which is selled in the market with certain composition,and by decrease the cycle of faps they fell much much better.It has been three years so I am anxious and started to search for possible modern medecine approach and finally was diganoed.Also, I even tried a india product called Night Fall cure capsule,which didn't work for me...The introduction of it is quite appealing.any questions about Chinese medicine is welcome
