Sometimes, for a complete recovery it can take 4-6 months for the scar to heal and sutures to be absorbed. It is better to wait it out, take some crocin if the pain is unbearable sos only during the pain and carry on with normal activity. If after this time period the pain is not less, then you can consult for a scar excision of that area to be sure there is no nerve entrapped-which is rare. If your sleep at night is undisturbed, I would not worry too much since with time the pain should get less.
