About 2 years ago I went to see a ENT doctor for my sinus troubles. I noticed that I often found myself not smelling what others around me could smell, and these were strong odors as described, but I could not smell them. He prescribed me so nasal spray and an MRI. I tried the nasal spray, it did not help; and I avoided the MRI after it took 2 weeks to approve. Now a year later, I still really can not smell a lot of things ( because I live alone, it is hard to tell). But recently I have been experiencing more intense throbbing and pressure in my head in some specific areas. Should I go and get checked out or what.
