Stabbing/Electric Shock in My Leg

So, last week I got this pain in my lower calf. It feels like I have a cut there but there is nothing there, It could also be explained as an electric shock in my leg that last for a maximum 7 seconds. It doesn’t hurt when I walk. It is kind of random. I would say the pain rates as a 5 on a scale of 0-10. Any help would be greatly appreciated. Thanks in advance.

Search sciatic on youtube / google the problem is the lower back the nerve being pinched goes from there to your toe. All the best !
