I have discomfort on my right side from the hip flexor to the knee. I m very active, yoga, power walking, etc. I eat very healthy and am not overweight at all. This discomfort, not sharp pain is now causing me to go to bed with a heating pad. About 2 years ago, I had many acupuncture treatments and the acupuncturist thought it was a tight IT Band. I think it s more than that now. Any thoughts?
