NOT "love handles" - honest!

Options
I see, from following tips and links here, that what I thought were my love handles - are not.

What I have are a couple of extra lumps of . . . extra: above each buttock, in line with and behind my iliac crests. I can't really get hold of them, because they're not flabby, they're just . . . there. I don't need them there. I haven't always had them. They grew on me earlier this year when, because of big injury, I wasn't moving much at all. I want them gone. They've shrunk a bit but not enough.

Anyone know any specific exercises for getting rid of whatevertheyare? The rest of my eating-programme and exercise regime is having the required effect in various other places but not on these thingummyjigs.
