Thanks for providing more information.
I understand your condition.
And in my opinion your symptoms can be related to Eustachian tube blockage.
As you feel popping sounds in ears,nose,pressure in head so when eustachian tube( tube that links the nasopharynx to the middle ear which maintains the air pressure between nose and ear) blocks then air cannot then get into the middle ear. Therefore, the air pressure on the outer side of the eardrum becomes greater than the air pressure in the middle ear resulting in popping sounds or noises.
So you need to be seen by an ENT specialist for a clinical examination for further evaluation.
If your ear examination'll be fine then most possible cause of your symptoms is psychological and you may require some anti-depressant in low dose.
Even your blood pressure should be monitored.
Otosclerosis (stiffening of the middle ear bones),Allergies,Thyroid problems,Certain foods such as soy, wheat, chocolate and red wine,Anemia are other possible causes.
So it is advised to undergo Complete Blood Count,ESR,Absolute Eosinophil count,Thyroid function test for further evaluation.
Try sleeping with your head propped up in an elevated position which lessens head congestion and noises may become less noticeable.
Take OTC Decongestant or Antihistamine tablets.
Try Valsalva manoeuvre.
-Take a breath in. Then, try to breathe out gently with your mouth closed and pinching your nose. In this way, no air is blown out but you are gently pushing air into the Eustachian tube. If you do this you may feel your ears go 'pop' as air is forced into the middle ear. This sometimes eases the problem.
Avoid alcohol, smoking, caffeine.
Do meditation and deep breathing exercises.
Avoid loud noise as well.
You can ask your doctor for masking devices (Tinnitus maskers )similar to hearing aids, these devices produce a continuous, low-level white noise that suppresses your symptoms while sleeping.
I hope this helps.
