Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand..
As per your complain pain in jaw on the side where you have got dental treatment done can be due to pain originating from the tooth that is worked on and the pain can radiate to the entire jaw on the same side..
While pain in neck on moving it side to side can be probably due to stiffening of muscles and also
swollen lymph nodes under the jawline that can be a cause for
neck pain..
If the nerve is hit then in mild injuries the nerve recovers rapidly and the symptoms resolves and as you already have milder symptoms, nothing is there to worry..
Nothing to worry as the pain is mid and will resolve gradually..
As of now you can anti inflammatory painkiller like
Ibuprofen and also
muscle relaxant like Chlorzoxasone..
Do cool compresses..
In case if there is no improvement or the symptoms worsen consult your
dentist and get clinically evaluated..
You can also discuss in detail with me by going to my profile and ask me a direct question for detailed discussion and advise..
Hope this information helps..
Thanks and regards.
