I've also had meralgia paresthetica on my left leg from wearing tight squat briefs that eventually went away.
Sometimes issues can be circulatory, but to me, it still sounds more like you tweaked a nerve. The big question is whether you're having pain. At the end of the day, however, it's best you're going to see your doc.
Oh, and be honest with him, letting him know you gave yourself an injection. He won't report you or anything, and that will be the only way he can properly diagnose what's going on. Most of the time, it's obvious to doctors anyway.
Good luck, and hopefully it's something that clears up very soon.
