I think you should go to your doctor, it might be a sinus infection in the head which causes sinus headache or sinusitis. There are many signs and symptoms for sinusitis, if you have some of the symptoms, then go visit a doctor and hopefully it won't be anything serious.
Sinuses are up your nose to almost your forhead. I don't believe they are in your head. I think they are connected to your nose.
You are probably stressed. This could be a matter related to sinuses.
It could be your rear main seal or head gasket...is it coming from higher or lower. Higher could be head gasket, lower from rear main.
A lump on the back of the head could be a simple knot from hitting your head on something like a cabinet. It could also be a cyst. A doctor is the only person who can diagnose the lump.
There are a number of possible causes for feeling pressure at the back of the head. They include tension headaches, migraines, headaches originating from the neck area, and inflamed sinuses.
yes
Well all the symptoms that you have described seem to point typical sinus problems and even a sinus infection.Pressure in the head can be due to congested sinuses. When your sinuses become congested they build up pressure in the head and this in turn also results in your body draining mucus down the back of the throat (this condition is known as post nasal drip). When your mucus is infected and it is drained down the back of the throat it ussually leads to a sore throat/ throat infection. The pain in the ears is also as a result of the congestion, because your ears are connected to your sinuses throuth the eustachian tube. When the sinuses become congested we ofte nfind that our ears feel blocked. When there is a sinus infection we may even get earaches.
Proper posture, relaxed jaw and throat muscles, and good breathing technique can help to lighten the head and provide resonance for the voice. It is important to maintain alignment of the head, neck, and spine to optimize vocal production. Exercises such as humming and sirening can also help to create resonance in the voice.
upper neck / lower head
Possibly a migraine headache?
it could be an ingrown hair.
The lower posterior region of the head corresponds to the nuchal region, which is the back of the neck area where the head connects to the neck. It is located below the occipital region of the head.
