Thank you for replying Mark. Its hard to define the taste, its a little salty but more metallic and is definitely correlated with a feeling of pain (almost tissue tear feeling) between the base of my skull and C1. It comes on during the second half of the day, but will come on earlier if I do an activity which involves moving my head alot and flexing the skull/C1 section.

Has anyone here had experience with whiplash and a CFS leak?
