Hi, I am Dr. Shreyash Mehta, MD Community Medicine.
I understood your query, I hope my answer will solve your query
As you told you were hit on the back of the head on pavement.
You told that you do not have headache and your vision is fine.
You have some
nausea and part where you have been hit is sore.
Ultimate diagnosis requires examination.
From the history it is mild
concussion with some
contusion.
The swelling shall appear later.
You should keep your head in upright position. Take rest
You can take
Cap (Omez 20 mg+
Domperidone 10 mg)-one daily morning for 3 days
tablet with combination of
Aceclofenac 100mg+
Paracetamol 500 mg+ Serropeptidase 15 mg. for decreasing local soreness-maximum thrice daily for 3 days
I think you should be okay after a rest of 2 days.
You should contact the doctor if following symptoms appear
inability to wake up (also called a coma)
seizures (
fits)
draining of blood or clear fluid from the ears or nose
unequal pupil size (one pupil is larger than the other)
