Sneeze pain after 2 week of appendectomy

I had a laparoscopic appendectomy done on 13th November. I can walk now normally and have no digestive issues or gas problems or any swelling or infection at the incision sites. But since 3 or 4 days I am having shooting and stabbing pain at the bottom right abdominal incision sometimes which also radiates behind the incision site around the waist and pubic area.When I am sneezing,it is aching there,like shooting pain which is radiating to upper thighs and hips,for few minutes and then back to normal.Is there anything to worry about?I had a 1 week follow up checkup and doctor said i am fine. Also,Could you please answer is there anything to worry about in future if I had appendicitis,as I worry it can be caused by something else.My biopsy reports are normal.Thank you,please help doctors.
