Thanks for using HCM.
Firstly you have not followed the advise for surgery which would have removed the appendix
once and for all. However since the appendix still remains, its prone to repeated attacks of inflammation and causing symptoms which you are having over and over. Complications such as bursting of appendix can occur considering the appendicitis
progresses to further stage. Advise would be to consider a near date for surgery, since avoiding it would pose more problems for you rather than a solution. Only taking Augemtin would not help fully.
Feel free for further queries.
