My left ankle hurts when i try to stand on my tipy toes or were heels could this be a pinched nerve or something to do with my muscle?

Probably not nerve: Possibly the muscles that stabilize the outer ankle could be involved. You probably should be evaluated by your local podiatrist.

Could be either: You should see a podiatrist for an exam to determine what the cause is.

It would be : Important to know the precise location of pain. Could be a few problems i.E tenosynovitis of the flexor hallucis longus if the pain is in the back of the heel, a talar dome lesion (like a bone bruise to the top of the talus bone.) you need a clinical exam (bring your heels with you for the visit.).
