Nerve defect an the eye problem. One.

For like 1-2 months I'm having thus nerve sensation above my left ear, and 'm having a pretty bad left shoulder pain for 1 year .Now I am feeling for like 2 days or so that I am seeing far away things a bit dizzy in my left eye... Consulting a neurologist he said it's a psychological nerve defect . I can see clearly in both of my eyes .. But only wid my left eye 'm having this defect . I also have a morning sickness , I vomit after brushing most of the morning and have  excessive stress problem . I also have a lil kinda pain beside my left ear on the cheek bone and I have frequent cold attacks...I haven't ate ice cream for like more than a year and am having a pain in my throat too.. One doctor said that it's for the cold and the other even after checking my retina ( the neurologist) said it's a nerve defect and made me have some tests like MRI , ECG and another one...
