The first character is the word "tòng", which means pain. The character itself is made up of two parts, one is for disease, and the other is for pathway, or something we move through.
痛 病 必 瘀
Tòng bìng bì yū
The treatment strategy is obvious and easy, we reestablish movement to the pathway! ...And that my friends, is Acupuncture 101.
When treating pain, we also take into consideration 1) how long the blockage has been there, 2) how severe the pain is, and 3) the general state of health. The answers to those questions help us develop a treatment plan (a.k.a. how many visits it will take to make it go away...).
