A member asked:

I have severe lb/glute pain primarily on left side.l i noticed a (fluid like) lump on sacrum bilaterally but larger on left. what could this be?

A doctor has provided 1 answer

Get a scan: The differential diagnosis would include fat necrosis, partial or full disc herniation, sacrococcygeal mass, cutaneous tumors, and poorly exercised paraspinal muscles. I suggest you see a physical therapist to have the area evaluated and go from there, if the answer is not simple an MRI may be needed to identify what lies beneath the skin for diagnosis and therapy
