Would my front tooth Root Canal be painful ?

One of my front tooth got chipped off around 6 years back. I did go to the dentist the same day , and he told me to have the root canal done since he spotted an abscess . But I denied to do it . In the past 6 years , I've had several gum boils , but since the last 2 years I haven't seen any. Tooth ache's are rare . I do have a tingling effect behind the chipped off tooth spreading the upper jaw. And also , whenever I have a tooth ache , I experience the pain in the adjacent tooth too , the pain is almost identical for both, don't know why . I would like to have the root canal done , and so my questions are :

Would it be painful or more painful actually since its been 6 years which I think would be a rare case.

Would there be any other complications compared to normal root canal since its a front tooth ?

I am really anxious to know about it , and also I am a person who is really scared of such surgeries . I hope they numb me really hard !

Thank you
