Is it normal two weeks after a Botox treatment to develop pain at the injection site? (photo)

I had A Botox treatment with my neurologist two weeks ago now to help with migraines. The spot right between my eyebrows has been numb and I understand that is normal but the last two days it’s been really sore even the most gentle touch is so painful. Is this normal two weeks afterwards or do I need to get it checked out?
