Pain in upper tibia

[joseph_norton]

I have a dull but non stop pain in my tibia and lower thigh. it streatches from half way down my calf (although the pain isnt particularly in my calf muscles) and streatches up to about 4 inches above my knee on the inside of my thigh. The pain skips my knee.

When running (about twice a week doing 4 miles) it hurts and somtimes gets to the point where i cant move. it is not a stabbing pain but more like an extreeme growing pain.

When i strectch this hurts it, make the pain better for a while, then it comes back.

I am quite young (17 nearly 18) and relatively fit so this should rule out some diagnostics.

Could it simply be growing pains or should i have it checked out?

Thanks,

Joe
