Would anyone know why one would feel tiredness in one leg only while running?..
I have been experiencing this problem going on 10 years now... My left leg only gets tired- particularly when going up hills.. The symptoms do not occur while riding a bike or doing the elliptical, just running... I still persevere through runs 2- 3 times a week, but the problem makes takes the joy out of running, is distracting and annoying- but not painful...
I should mention I've had a bulged disc on that side since 2001, and the symptoms did not start showing up till '08... I did not have this problem at all while running through the 80s and 90s...
Any advice would be greatly appreciated!..
