Hi Lilrunaway,
Sorry you feel bad...good thing is we all feel your pain here. I was recently diagnosed with a labral tear after having what I thought was a pulled groin. Since then I have done hours to days of homework on everything from labral tears to impingements to MRI's and surgeons. I can answer your questions from what I've experienced and read. Hope it helps you some.
1) Referred pain. Absolutely you can/will feel pain in your low back, front thigh, groin, hip area with a labral tear and other hip injuries. Personally I have deep groin pain, front quad pain and low back/butt pain. If I move suddenly or laterally I get shooting pains up through my eyeballs. Sleeping is really tough, so is sitting and driving. Besides the labral tear I have some bursitis and tendinosis so I suspect it's widespread for all those reasons.
2) Xray. One thing I have read SO many times is that people are not diagnosed right. An x-ray will not show a labral tear. It could show an impingement (which is basically a change on the bone) but the only way to see a labral tear is with an MRI with contrast or with the actual hip scope. I don't think a CT scan shows it either but I may be wrong on that. It seems many physicians out there don't know about labral tear symptoms, don't ask for MRI's with contrast and usually say it's nothing. I don't get it...I picked the right Dr. initially who suspected the tear on my first visit and ordered the MRI/arthrogram which confirmed it. My sister's sister-in-law suffered for 14 years before being correctly diagnosed.
3) MRI. What are you nervous about...the needle of the arthrogram or the MRI tube? I was very surprised how uneventful the arthrogram procedure was. It wasn't exactly comfortable but if you get a good Dr. to do it, it wasn't that bad. I shattered my wrist last year so nothing has compared to the emergency room pain when they had to set it...that is my comparison pain and nothing has come close to that. For me the wrist set was a 10 and the arthrogram was a 2. I am a little claustrophobic so I did take some valium before going in the tube. I asked to go in feet first and it helped alot, just make sure you are comfortable on the table before they leave the room because you cannot move inside the tube.
One other thing. I did have a slight allergic reaction to the contrast dye 4 days after. I got a skin rash that ended up feeling like poison ivy. It made me a little nervous but was nothing big in the end.
I have done a national (no joke) search for the best surgeons to do arthroscopy. I want/need to be able to run again so it has become my focus to get healthy.
Good luck. When is your MRI? Make sure you write back what the findings are.
