Welcome to HealthcareMagic
I am Dr. Shama and I will be answering your question.
I went through the history and it seems you are having severe headache
. The common causes for severe headache are sinusitis
, dental problems, refractive errors of the eye....
Sinusitis is usually associated with pain around the nose and eyes, cold, cough
Since you are not having these symptoms it looks like sinusitis is not the cause for your headache. The swelling behind the head is not related to sinusitis and requires evaluation by CT scan
to find out the underlying cause.
Do consult your doctor for examination and treatment accordingly depending on the underlying cause.
Do write back to me for further questions.
Hope this is helpful yo you.
