I feel like I'm losing my mind because I smell fantom smells then get dull headaches from it. For example, for the longest time I would smell, what reminded me of the zoo. No one else could smell it, but I would then develop a dull headache across my forehead. There were times when I would smell a stale ciggerette smell for days, and along with it, the same headache. Again, no one else would smell this. Today, I smell a sweet but bitter perfume smell, and the same headache. Along with all of this, my sense of taste comes and goes. I have seen someone that said I have what looks like nasal polyps, use claritin and flonase and you will be fine. I dont think I am fine. What do you think?
