Ghoti- the best advice you have received here is in 2 areas:
1] shut him down
2] try to find another doc, who specializes in sports med or who will send you to one
XRAY is for bones, MRI is for soft tissue
"MRI is the method of choice for the diagnosis of many types of injuries and conditions because of the incredible ability to tailor the exam to the particular medical question being asked. By changing exam parameters, the MRI system can cause tissues in the body to take on different appearances. This is very helpful to the radiologist (who reads the MRI) in determining if something seen is normal or not. We know that when we do "A," normal tissue will look like "B" -- if it doesn't, there might be an abnormality. MRI systems can also image flowing blood in virtually any part of the body. This allows us to perform studies that show the arterial system in the body, but not the tissue around it."
ALSO
"Why would your doctor order an MRI? Because the only way to see inside your body any better is to cut you open. MRI is ideal for:
Diagnosing multiple sclerosis (MS)
Diagnosing tumors of the pituitary gland and brain
Diagnosing infections in the brain, spine or joints
Visualizing torn ligaments in the wrist, knee and ankle
Visualizing shoulder injuries
Diagnosing tendonitis
Evaluating masses in the soft tissues of the body
Evaluating bone tumors, cysts and bulging or herniated discs in the spine
Diagnosing strokes in their earliest stages"
You can't do any of this with an X-ray. X-rays show bone issues.
Try to find a doc to refer you to a sports med doc to get an MRI. Resting is good, only if that will cure the problem. Coach Chris is correct in that you have to find the root of the problem [i.e the cause], but until you find out WHAT is wrong, you might have a hard time figuring out what caused the problem to begin with. Very few of the people on this site are certifiable experts in anything outside of baseball, and most of those are self-proclaimed
, [although many of us are certifiable, period]. Ask for advice, but be wary of email/remote diagnoses of health related issues, especially as they relate to your children.
REPEAT - find a doc who is willing to work with you, to get the MRI or at least to explain WHY you don't need one.
CAVEAT: MRI's don't always tell the whole story, although they do a great job. I had a 30% tear in my rotator cuff - X-ray showed nothing, MRI was inconclusive. After a full year of rehab and minimal results, the tear was only discovered when they cut me open.
Good luck
