Hello and welcome to the forum. Thanks for your question. It would be helpful for what the three diagnoses were. Why did you not trust any of the doctors to seek different opinions, if I may ask? A lot of times, an electric shock feeling in the legs or ankle would be due to damage of the peripheral nerve. It can also be due to disruption in the lumber spin for electric shock feelings in the leg. More information would be helpful such as your symptoms and what proceeded this.
