Right sided pain - groin, pelvic and lower abdomen?

For years, off and on, I've had an unexplained right sided pelvic pain.
This recent bout started after I pushed and pulled a heavy sleeper sofa across a carpeted room back in July.
I started getting right sided groin pain, pelvic and lower abdmoinal pain and aching up into my ribs.
Went to the doctor - he ran a Cat-scan to see if my appendix was acting up. It didn't show up on the scan so he said it probably wasn't inflamed.
So, I have tried heat, ice and the like and yet I still have this pain. Went to the gynocologist - it is nothing there - no ovarian cysts or other problems.
Some days it is better than others and if I sleep in the right position at night, I'll wake up pretty good until I move around. Sometimes, it aches all night. Some days the groin hurts worse and some days it's mostly pelvic pain.
Any thoughts that anyone might have would be appreciated. Thanks.

A thought. You may have either an inguinal or femoral hernia. A buldge need not be present, the pain is intermittant, it was worsened by physical exertion, a hernia is very possible. I suggest you visit the website of North Penn Hernia Inst. They have a board where you can describe your symptoms and Dr. Goodyear will answer your questions. I had a right inguinal hernia repaired 4 years ago and now have a left one so I do know what the pain is like. One more thing the pain may be referred meaning the pain may not be at the site of the hernia but remote.
