 [ Symptoms ] was diagnosed by the doctors as “periproctic abscess over 9 oclock in ssl” [ Disease ] hi getting the dressing changed in a 7 days time can itself be a cause of infection at the site of surgery so it will be better to get it changed daily or atleast every alternate day you can change it on your own only if you have the expertise to follow proper aseptic precautions it will be better that as of now first you should go to your surgeon and get the dressing changed and if not possible you can consult an emergency service if placed properly it will not come off on its own hope this helps
