Hi, Iam having pain between my hips, just to the side where spinal cord ends from past 6 months. It diminishes but appears again when I sit in a relaxed posture or when I travel for long. There is a slight bulging, like a boil above which I can observe a Blotch. Yesterday I observed Pus from the Blotch on pushing the bulging spot.
What is it, help me.
