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
