[|Human|] Hello, For about 3 continuous days now, I have been feeling this very odd sensation in my lower leg. The exact location would be where my Peroneus longus muscle is located. This sensation is only felt on my left leg. I can describe this strange sensation by comparing it to a pinch of electric shock at the same exact spot whenever I stretch my leg. It usually occurs when I bend my upper body towards my knees without bending them. There are two major changes in my life, I must say. 1- I stopped smoking cold turkey, it s been 10 days all together. 2- I ve started working out very intensely. Sometimes I stay for 3 hours long at the gym. The is first time I get such a strange feeling. Your help is appreciated :) Mimi
[|AI|]  Hello, On back of our leg starting from middle of our hip, we have a thick nerve, which passes from the middle of the thigh to the back of the knee. This then divides in two parts, one part goes anterior in leg by encircling our outer bone at leg and other at back of leg. As you stretch your knee without bending it, the these nerves stretch out. Due to friction at some hard area in there, you feel such electric sensation. It is normal in nature but excessive stretching should be avoided. You should gradually do exercises and with time your body will adapt. Hope I have answered your question. Let me know if I can assist you further.
