My lower left leg feels stiff and sore...?

....last Wednesday, I experienced a searing pain in the middle of the sole of my foot - in the arch - like someone was pushing a screwdriver handle into hard. It lasted only a couple of seconds but it stopped me in my tracks. Since then, my leg has felt stiff and sore and playing football has been difficult. Any ideas?

Sometimes pain,stiffness and swelling is signs of heart trouble.
