Hi,
thank You for contacting HCM,
Trauma to the head , depends on its nature can cause several problems i.e. headache, nausea, vomiting,
memory loss, blurring of vision,
dizziness, fits even
loss of consciousness etc.
There are two impacts of any force--Direct and indirect, due to the direct impact at the site of the force(in your case by direct hitting) and the brain inside the skull suffers the injury while indirect
head injury happens due to indirect trauma to the brain
Well as for your query yes its certainly related to trauma to the head which can not only happen to repeated trauma but also due to a single trauma alone.
If you want my opinion ,its better to get in to your nearest ER or check with your
neurologist for a thorough neurological check-up and probably get a CT-Scan of the head done
Hope this'll help you, thanks again for contacting HCM , let me know how things go..
