Is Stinging Pain Or Pain Where I Had Stitches Normal After A Major Surgery At The Abdomen?

I had a colonascopy in August 2022, 2 benign polyps removed. However they found a polyp at the secum which they confirm was precancerous and appendix was growing or grown into seccum they said is very rare. They removed seccum about 2 inches above secum intestin and appendix. That was in November 2022. Now bowel movements are 3 to 4 times a day at times. Also I get either stinging pain or pain where I had stitches. Is this all normal? Thank you.
