Did this ever get resolved for you? I got a phenegan shot 5 weeks ago in the side of my hip and immediately told the nurse that he hit something, it felt so wrong and hurt so much, worse than any shot I've ever had. It's still not getting any better and after reading about this medicine I'm starting to get a little scared! And the shot was given directly in the side of my hip, when my arm hangs straight it lays directly over the injection site.
I would reccomend seeing your primary physician or going to a walk- in to get checked out and referred
