If I have an hernia ingunal of 11mm, do you recommend surgery? Otherwise what treatment do you recommend me? Many thanks. I also have pubalgia

Hernia. Not necessarily. If it does not bother you, is not increasing in size and does not incarcerate (get stuck) then you do not absolutely need to fix it. If, however, the above things are happening or it is a larger hernia thru a small defect in the muscle then it is better to fix it early vs later.
