An interesting yet very common symptom of Liver Qi Stagnation is something called Plum Stone Qi.
This is when you have a sensation of something caught in your throat but there is nothing physically there.
When we break up stagnation and release stuck emotions this sensation goes away. Techniques used in Traditional Chinese Medicine such as acupuncture, herbs, cupping etc. can be an effective way to break up the stagnation and relieve the sensation in your throat.
