I recently developed some hip pain on one side, which I'm 100% sure is caused by cycling, especially I felt it more after yesterday's long ride, and the area is exactly the part that drives my pedaling the hardest when I'm riding up a slope (or raise the gear). From the anatomy pictures, it seems to be around the head of the femur (where the hip connects the thigh). It's only the left side that hurts, and when I'm in certain positions or make certain movements. I'm riding a hybrid bike in upright position. I can't figure out what's wrong with my pedaling, but apparently something improper, since you are not supposed to have such pain just because of pedaling hard?
Any clues/tips what's the problem and how to correct/avoid it will be much appreciated!
It's nice and sunny and warm today and I wish to ride more
