question: Hi, I have what feels like a lump in my hip felxor, pretty much in the crease between lower abdominals and top of the quad. One on the right hip is slightly larger than the one on the left hip, and are not in symmetrical positions. When I press on either one they move around slightly, and no real pain just minor discomfort. It almost feels like a knot in a muscle. What could these be? Should I be concerned and should I seek further medical advice?
