thank you for your query.
My opinion is that is the the mesh that was inserted that is causing the foreign body sensation.
The mesh sometimes gets displaced and would impinge on the pubic bone, causing such pain.
Also, sometimes it might slighly erode through, leading to such pain.
Unfortunately, the only way to know whats exactly happening is to have a diagnostic laparoscopy
or a laparotomy
and visualize the area.
You would also do well to evaluate yourself for urinary problems.
calcium and vitamin D deficiency sometimes predispose to pubic bone pain
Consult your surgeon at the earliest for an evaluation.
