Possible wrong injection site

I received an IM injection of Rocephin at my physician's office today, and when his MA came in to give it, he gave it right above my iliac crest!!  NOT in my dorsogluteal muscle!  Was wondering if there was a reason for me to be alarmed (other than the pain in my hip!) as to any tissue damage from the drug itself?  Thank you so much!!
