I recovered from covid, 3 days later developed pressure on my nose, forehead, and temples. It has been going on for 9 days now. My neck also feels very tight. However my doctor told me a sinus infection although i don’t have congestion, i do have a bit of post nasal drip though. When i take mucinex it helps with the nose pressure but not the tightness around my head. I have tried massaging but it only helps a little bit. Idk what it is but it’s driving me insane! My head feels so heavy. Could this be a constant tension headache?
