Intraosseous lipoma

[Mriquestion]

Hi, I had an MRI about 18m ago for right SIJ pain and what turned out to be neurogenic claudication - it showed severe lateral recess stenosis at l5/s1 but also a small intraosseous lipoma on the sacral side of my right SIJ joint. No one seemed bothered about it and there's no follow up (i had an epidural steroid injection for the nerve root with good effect). I'm left with ongoing clunking in my right SIJ, doctors put it down to me being hypermobile but it only started doing this about three or four months after the birth of my 3rd child (now aged 2). It's definitely a clunk at the SIJ, I can place my fingers over the joint and feel it when I walk. My question is, should the intraosseous lipoma be followed up in some way? Could it be causing the clunk by in some way distorting the joint surface?? Or am I overthinking. There's some tenderness in the joint still, but the clunking is sore and I can't stand for prolonged periods without it being sore. I think the whole thing was glosses over because there was another obvious thing to treat on the scan, if that makes sense, and whilst my sciatic pain is much improved this ither issue persists. Thanks.
