Welcome to the forum. It has been over 6 months since you have had your appendectomy
done. Complications of appendectomy may present with surgical wound infection
or abscess formation but it does not appear from your symptoms that you are suffering from post-operative complications. However, you should get clinically examined and get all investigations done to remove any doubts. Contact and consult the treating doctor.
I feel that it is the anal fissure
that is causing you restlessness
. Use of laxatives like dulcolax with milk at bed time may be helpful for you, local application of bisacodyl
furoate oitment can give you relief, you can take warm sitz bath twice- thrice a day.
However, get examined by a doctor to determine and assess the degree of fissure/haemorrhoids from which you are suffering so that you get treated appropriately. Neglect may worsen the anal fissures. Take care.
