I have an allergy for dust mites and about two times a year the symptoms get much worse. Just like it did two weeks ago. But now when I cough I suddenly have to endure pain in the back of my head at the height of my right ear, but a bit more to the middle of the back of my head.
I added a photo to indicate where the pain is.
It feels like it stings me and then the pain stays for about 20 minutes. After that it slowly drifts away.
It is the worst in the morning and in the evening and it is getting worse by the day.
I am a 19 year old guy.
