For this, well need help of the other symptom, the face. To me, it looks likes the pain and hypersensitivity to touch as seen in
Trigeminal Neuralgia. You have described the facial pain in exactly the manner in which Trigeminal Neuralgia strikes.
I am concerned here. If this is trigeminal neuralgia, and you do not have any other indication that would tell that this is a herpes virus infection, the next option is MS. I feel this should be kept in mind and ruled out accordingly.
