Hello Dr. Rynne. I Am Experiencing Pressure On The Left

Hello Dr. Rynne. I am experiencing pressure on the left side of my head, above the ear. I also have upper neck pain. I have been experiencing this for one week. I took one dose of Sudafed PE thinking it might be sinusiti. However, I do not have any mucus or pain on my forehead or below my eyes. Thank you.
