Approximately 2 months ago, after 5 days of strenous exercise and volleyball, I developed a pulsating/electrical zap on the innner side of my right foot near the arch. Playing any sports caused the zapping to get worse and radiate throughout the foot, toes, ancle and calf. After lots of rest, this sensation got better although will not go away, some days its there and some days only a light tigling. Sitting make the symptoms worse and walking, standing, or lying down seem to improve symptoms. Ive had a clear EMG, Lumbar MRI, X-rays, neurolgical test. Im 31, and an atheletic male. Thanks for any assistance.
