My hernia surgery wound hurts. Do I need re-surgery?

Hi doctor,

I had a right inguinal hernia surgery, four years back. But still, I have troubles in the surgery wound, especially when I am involved in harder or longer physical activities. I also get hurt if lying down on the side of the surgery. The doctor advised me to get a CT scan, but as I had in the past took three CT scans on other parts of the body, I am not willing to take the risk of radiation. When ultrasound was taken, no abnormalities were detected. So, please advise what should I do or how should I take care of it. I am even thinking to have a re surgery, if necessary. What are the problems or risks I may face if re surgery is done? Thanks.

Thank you doctor,

An ultrasound was done, and the hernia has no problem, it is fine? What is suspected is something must be wrong in the wound like mesh entrapment or others. Kindly tell me the dangers or risks of having a repeat surgery or is it just the same as the first surgery? Thank you.
