synesthesia or hypocondria

I think that I suffer from some sort of synesthesia. If injure myself around the head and shoulders area and sometimes when i receive a shock, my first sensation is the smell of burnt hair then the pain. I did have a bad drinking problem for about ten years and the doctors thought I could have caused nerve damage related to other issues but my MRI was all clear. The doctors are sick of my now and dont take me serious anymore.I have another neurological problem which the doctors tell me is not heard of. Generally the left side of my body is colder than my right, one doctor observed this and said it could be a psychosematic effect on the nervous system. I was thought to have pre senile dementia at one point, MS at another.Now they just dont know and have given up. If I told my doctor I was an Hypocondriac he would say it was all in my head, probably.
