I have cervicogenic migraines and a history of cervical spine surgery (c4-c6) which caused more issues plus occipital neuralgia. I had a very red left eye with different head pain than my usual. I ve had severe neck and head pain only on left side for 5 days now. face feels a bit numb along with severe jaw and cheek pain. double vision. left side of face starting to hurt in cheek/upper jaw area.
