Hi mariaamitha,
First, I want to welcome you to the Pain Management Forum and let you know that we are glad you found this Forum. I want to let you know that there are NO Doctors on this Forum, only CP {Chronic Pain} Patients that help each other with our OWN expertise and experiences that we have developed through our OWN CP Issues.
I'm so sorry that you are having this pain in your left eye. I'm sorry that I DON'T have any answers for you BUT I would recommend that you re-post this question on the Eye Care Forum.
Here is the link:

Of course you are ALWAYS welcome here on the PM {Pain Management} Forum but for this particular question you REALLY do need the Eye Forum. :)
Best of Luck to you............Sherry :)
