Thank you for that additional information.
Well, first of all, tobramycin is not the correct treatment for pink as this is caused by a virus....
That being said, I do not believe you have pink eye.
You probably have uveitis (inflammation of the inside of your eye) This would explain the long course, light sensitivity, small pupil and pain.
Uveitis can be caused by many issues....all of them beyond a nurse practitioner or optometrist ability to deal with.
So. What should you do?
I suggest you get into for a complete eye exam by an ophthalmologist (Eye MD) tomorrow morning. I am sure if you call around there is one in your area who can squeeze you into the Monday schedule. I do not see a need for you to go to the ER tonight as the only value of such a visit would be if they had an ophthalmologist on call to treat you....and for the $2K such a visit would cost an office visit tomorrow will be just as good.
Does this make sense to you?
It's safe for you to press the positive feedback button now if you so desire. And, never fear, even after you press that button I'll still be right here to continue helping you, but, as I do work for tips, I want to make sure you are happy before rating me.
