The rule is that even a low voltage shock should be evaluated by an EKG. The reason is that it may cause heart abnormal electrical activity called as arrhythmia. With the symptoms of sweaty, rapid heart rate and mild headache, shakiness immediately after the shock, this is further necessary. The feeling of pulse from ankle to knee can be muscle contractions due to electrical shock and can cause increase in the compartment pressure in the legs (termed as compartment syndrome). Though with your manifestations this has a very low chance. But we work on the highly cautionary side with these symptoms and since EKG would be advised just for the screening, it is advised to go to ER for an evaluation. Again, just to re-emphasize, these symptoms may not be anything serious, but any symptoms post shock need physical exam and an EKG.
