Thanks for writing in to Healthcare Magic!
It is both.
You did not tolerate the injection and probably the injection have been given around a nerve
so it has resulted in benumbing of the nerve.
The pain may last for about a full months time.
You can take oral antibiotics
and pain killers for all your problems but under supervision of your physician.
If you have any further query please let me know I would try to answer it for you.
Wish you a great health!
