Dear friend, welcome and thanks for entrusting your query here at HCM!
I am Dr. Prasad Akole (Critical Care Expert- http://bit.ly/Dr-Prasad-Akole) and am glad to address to your query here.
It is not normal to feel dizziness
But it is not impossible. It may happen due to general weakness from the severity of appendicitis
and surgical stress
Was it a complicated appendix?
Also dizziness could come if BP is low. Did you check it?
Is it on getting up from sleeping/ sitting position?
Did you have fever?
Are you anxious and tense?
Relax and watch if you again get dizzy. If so, please get yourself checked up.
I hope you are fully satisfied with the guidance I gave.
Hope I have answered all your questions. I would be glad to answer any further queries. Please ask for any clarifications before closing and rating this answer.
Thank you and Good luck!
