Persisent groin injury – sports hernia , osteitis pubis , groin disruption

I got a groin injury back in october, i kept playing football every other week until decemeber.

Ive rested since and its got much better

Im pretty sure its either
sports hernia , osteitis pubis , groin disruption

or a really BAD abbudctor strain my doctors and pyshio’s keep telling me its an abbudctor strain(i dont think they believe im actually resting)

its on my right side and i also have a slightly knocked knee on that side.

when i see the doctor they keep saying i dont have an adductor strain and its probably not a sports hernia etc , because there rare but dont give me a definite reason why its not them. How do i get diagonosed properly ?

and how long will i have to wait for the op on the NHS ? and approximately how much is an op outside of the NHS.

Im currently waiting for an MRI but from reading this site

http://www.aafp.org/afp/20011015/1405.html

i dont thinnk this is going to help diagnosise.

any help?
