When a flow of Qi in meridians is stagnated the affected organs will malfunction. In case of liver Qi stagnation, one typically feels distending pain along the sides of the body (especially in the chest), easily gets upset, depressed, and has irregular, painful menstruation or swollen breasts for woman.
That's what TIM just told me - apparently I have Liver Qi Stagnation (he is a Chinese herbalist as well as a masseuse). I looked it up when I got home and saw all my symptoms staring back at me. I didn't mention the chest pain or the PMT to Tim, in fact he told me my liver was stressed after 30 seconds of feeling my back, shoulders and neck.
I'm off to the Chinese herbalist in Chinatown to get the potion to fix me up. It's called Jia Wei Xiao Yao Wan.
My cynicism just kicked in - that description above would probably apply to 90% of the female population so it might have been a lucky guess. No matter - anything is worth a try - can't hurt can it?
