Cacosmia: It is the perception of a bad smell without an odorant stimulus. Overall, the most common causes of primary olfactory problems are aging, nasal and/or sinus disease, prior viral upper respiratory tract infections, and head trauma. However, it is important to ask for a consultation with a ENT surgeon or a neurologist to determine the cause, since some neurologic diseases can cause this too.

Migraine: While olfactory or smell related aura is not recognized across the board in migraine, there are many case reports described as such. Given now the fact that your symptoms are daily and likely disabling seeing your doc would be recommended. A brain/ sinuses imaging study will likely be needed.
