Hi. The sutures will dissolve, but they take longer to dissolve in some people than others. Definitely massage the sensitive areas as this will help the sensitivity and the scarring to resolve as quickly as possible. Regards Dr Charles Cope
At just 5 weeks post labiaplasty, some absorbable sutures may still be present and may take a few more weeks to desolve. Also, at 4 to 6 weeks scar can be thick and tender and can cause the symptoms you have described. You doctor is correct that massaging the area may help speed the healing process. You might ask your doctor if he/she would also recommend using a topical hydrocortizone cream which may also help. best wishes.
Some dissolvable sutures take longer than others to break down. Depending on the suture type you could be looking at another month before all the material is gone. At that point, its likely your symptoms will improve. Good luck
