Hi,
Thanks for writing your query.
After reading your post, it seems that there might be a possibility of
concussion injury as a result of the impact.
Spasm of the neck muscles due to injury can also result in the pain experienced by you.
I would like to suggest to you that you should get an CT/
MRI of your head and neck done.
Give complete rest to your body. Avoid watching television/computers and text messaging. Also avoid driving.
Pain killer like
Ibuprofen one tablet twice a day after meals along with an
antacid will help in relieving pain.
Local application of pain relieving gel after hot fomentation on the neck may help in decreasing pain.
If the problem persists, get yourself examined clinically.
I hope this is helpful to you.
Thanks.
