Welcome to icliniq.com.
I have read your query.
I am sorry for such discomfort you are having due to the hit on the head.
A concussion is an injury to the brain that results in temporary loss of normal brain function or level of consciousness, that results from mechanical force such as a hit.
The common symptoms of concussion include confusion, headache, nausea or vomiting, dizziness, visual disturbances, ringing ears, trouble in getting sleep, memory loss, or a brief period of amnesia or forgetfulness.
Do you have any bump over the head due to the hit? If yes, is that swelling big enough or reducing in size?
How hard was the hit against the wall?
In the history of symptoms which you have mentioned, you only had headache after the accident and you get proper sleep after taking the tablet Tylenol (Acetaminophen).
Yesterday, you had a foggy feeling, headache across the top of the head and behind ears and symptoms reappeared today in the noon. You did not have any nausea, temporary loss of consciousness, confusion or altered behavior, etc.
I would suggest you take adequate rest and watch out for the symptoms if they get worse or persist, or any new symptoms add to the list. take medical help immediately. Take the tablet Tylenol (Acetaminophen) for the headache.
If there is any further progression of the present symptoms and if there is no relief after taking adequate rest or painkiller then please seek medical help.
Hope this helps you.
Take care of yourself.
