Should I have diastasis recti repair during recurrent umbilical hernia surgery with mesh? (Photo)

had an herniorrpamy a year and a half ago. The umbilical hernia is back and the parietal hole twice the size (3 cm). I have diastasis recti (3-4 cm), a previous c-section (3 pregnancies), asthma with ongoing treatment and allergy to some materials and NAIDs. A surgeon suggest hernia mesh and not touching diastasis while the other says full abdominal wall suturing and mesh is necessary. Scared of mesh as I didn't tolerate ankle plate and I'm allergic to materials, NAIDs...thank you!
