I get presure point pain in in different spots on my head close to the back of my ears. What is the cause

Sinus infections typically cause facial pain, similar to a headache, and other things like tooth pain and congestion. It sounds more like fatigue, which can be stress-related, especially if you find that your muscles are tense. Try applying heat to the painful area as well as trying to relax (I know, probably difficult).

Bky, I would say fatigue if it feels muscular or a headache.

As always however, it is best to check with your doctor.

Munoz1226 and Bky, if you want to be sure I guess you need to get an x-ray image for your Para Nasal Sinuses (PNS). However, I think the X-ray only can show problems with Maxillary and Frontal Sinuses. As far as Ethmoid and Sphenoid sinuses are concerned, I think it cannot identify those. But then again I am not sure because if you take the x-ray from right or left side (if at all that is possible) then it might catch them. A CT scan will catch all the detailed images of all your sinuses but I guess that is a bit expensive. The best thing is to consult an ENT specialist and find out what is going on.
