Most likely your gall bladder meridian is inflammed - this is connected to your liver..... liver is one of the main places that mercury will effect and be stored causing problems.

You need to do a gall bladder and liver detox

Probably homeopathic would be best

You will see this meridian around the ear - your jaw is in here also
