Thanks for writing your query.
After reading your post, it seems that you had suffered soft tissue injury
. Stiff neck
can be due to spasm of the neck muscles as a result of injury.
It takes few days to weeks for complete recovery.
You should take proper rest for speedy recovery. If the pain is severe, you can take pain killer like ibuprofen
one tablet twice a day after meals along with a muscle relaxant
like chloraxazone and an antacid after discussing with your doctor.
Doing hot fomentation and application locally of pain relieving gel will be helpful in relieving pain in the neck.
You should also investigate yourself for knowing the cause of your blackout and fall. You should get yourself examined clinically by a Neurophysician and get some investigatons like :-
1. Head and neck scan.
3. Blood sugar levels.
I hope this is helpful to you.
