Thank you for writing to us.
Yes I agree with you.
With the symptoms that you are describing i.e. headache that is progressively a little worse with multiple severe pains on the side of the head, feeling nauseous, all go in favor of the fact that you have most likely experienced a concussion
and now you are experiencing symptoms post-concussion.
These symptoms usually do go away in a couple of weeks to four weeks time but can stay longer.
For the pain you can take OTC Motrin
For the nausea
you can take OTC dramamine
If your symptoms persist or get worse then I would strongly recommend that you should have a CAT scan of the head done to make sure everything is okay.
