Is it OK to massage neck muscles if you get neck pain after Botox injections?

It has been two weeks with neck pain that has not diminished much. My Dr. injected a trigger point for a specific injection site that was even more painful and it took care of that, but the neck and shoulder pain is the same? I have been prescribed a 10 days of Tizanidine and Hydrocodone -acetaminophen 5-325....do not get relief.
