For the last month or so i have had a smell to myself that only i can seem to smell. I cant tell if it is coming from my ears or nose. It is a strong sour smell, almost resembling something dead or rotting. I also have been expeiriencing a strange crawly sensation in my ears, it feels as though i have bugs in my ears crawling around. Between the buggy feeling and the sour smell it is driving me up the wall. Any ideas or suggestions?
