whether you are being on the progress or not?if not ,i do not think you can recover by yourself without any treatment,because it will be harder to recover years later.
i hope you can luckily find an excellent acupunturist,who has experience about the disease.
let me answer your question:
firstly,it did work the same day as long as the remedy to the case is suitable.but as far as i know,the experienced doctor about the disease are few,even in china.or as a native of shanghai city,i wouldn't go to sichuan province for treatment.i hope i did not dispirit you.
secondly,the acupunture treatment do no harm for your health.take it easy!
