Pubic region pain on exercising/sneezing

Getting pain in right side of pubic region whenever I do any exercises or running. There is pain when I sneeze as well. It goes away if I do not do any exercises for a week or so but again comes back as soon as I start doing again. The pain is not much but it's there whenever there is any stretch in that area due to exercise/running/twisting/sneezing. I have already met with an orthopedic doctor and a general surgeon but nothing concrete has been diagnosed. From my own reading, i could find that these are symptoms of sports hernia. I also got a Ultrasound scan done but nothing came out in that. Kindly advise what kind of doctor should I approach. Any reference of a specialist doctor in this area will help.
