The left side of my face becomes numb from time to time.The part that becomes numb is the cheek area. The last time it happened I want to the hospital and they did a TIA test (asked me to do a series of things, no MRI) and Bells Palsy Test, and both came back negative. The doctor says it is most likely stress. I have looked up different reasons online and some of it points to my sinuses are blocked. I have no mucus that I know of but I have loss my sense of smell as of late. I was also cleaning up the bathroom at the time with that new green cleaner that is made from coconut oil. I had no speech slurring, no drooping, and no headache. I am going back to the doctor in a week. Could all this be my sinuses. I am a 23 year old Male, 5 ft 4 in, 205 pounds. I have high blood pressure but am taking lisinopril for it. I took my bp and it was a little high but nowhere near stroke high. I think I was just panicking. What could it be? I also have a misplaced and somewhat ingrown wisdom tooth on that side.
