Hi Soph,

Well done for wanting to get this checked out and not blindly listening to everyone who says 'it's just growing pains.'

Only you can tell if something feels 'not right.' But only your GP will be able to give a medical opinion. The chances of it being sinister are very low, because you are so young, but it definitely needs to be checked out. 

The GP is the most important appointment. But you could also make an appointment with a physio as well, preferably one that specializes in people your age. Their insight can be very valuable. It cannot, however, be a substitute for a medical opinion.

You will feel much better after the appointment with the GP is made. It is fear of the unknown which is worst.

Wishing you all the best, Soph. Harry
