I Am Super Sensitive Suddenly To Smells And Food Taste.

I am super sensitive suddenly to smells and food taste. I continually over sense smells, especially thinking that I have an odor and I don't taste food the way I should. I detect bad tastes in everything, even sweets. Therefore, I am having to force myself to eat. This is very disturbing, however I am wondering if it could be anything medical going on. Thank You
