welcome to HCM.
You say you have nerve pain
) above your left eye, but how could you be certain that it is nerve pain and not some other pain due to infection etc.
There is in fact a nerve traversing out from the orbit, in that region and could certainly be neuralgia, but to confirm it you will need to consult a neurologist
. After thorough examination of your nervous system, he may suggest some special tests to arrive at a diagnosis and treat the condition accordingly.
Do not ignore this pain, it may be significant.
Wish you all the best.
