When i put pressure on my right foot, why do i get a tight/shooting pain in my leg?

Nerve impingement?: An impinged long nerve in your foot, when pressed could cause your symptoms of nerve pain running up your leg. The source of impingement is the question: could be a cyst, a swollen ligament or tendon, a bone spur, or a calcification. You need to get your PCP to take a look and refer you to an orthopedist for evaluation and imaging.
