What Causes Headache And Pressure In Head Post Head Injury?
No relation to the hit. Tension type headache
Detailed Answer:
I read your query and I understand your concern.
From the description of the pain distribution and character the most likely diagnosis is that of a tension type headache. It is by far the most common type of primary headache (primary meaning with no identifiable cause), estimated to be experienced at least once by as much as 80% of the population. Stress is an important component of its genesis and frequently at the root of exarcerbations like the one you are having, so it's compatible with your situation.
Treatment consists in stress relaxation techniques and over the counter painkillers like Ibuprofen.
The headache is not related to the hit you got a month ago.
