Buckley,
Wait for your appt with the orthopod, he will send you for an Wikipedia reference-linkMRI with a gandolium injection, this will determine exactly what is wrong!
what country are you in? as Physio/GP'sand other allied health practitioners have access to MRI in certain country's.( saves waiting for orthopod )
If the tendon is partially torn then soft tissue therapy from any allied health prac along with exercises will help. If completely torn then you will need a minor op. hard to give advice on this until MRI reveals all.
Good Luck
C
