Pain an epidural site 3 and a half months postpartum?

I am 3 and a half months postpartum with my second baby and the past few days I have had pain in the exact location where I had my epidural. It’s tender to touch and causes a dull pain when I move or lay on my back. I never experienced this with my first baby so not sure if it could be from the epidural or if it’s something else. Has anyone else had this?
