I have found two small lumps under the skin by my right hip, where the leg bends. They dont hurt. One is probably as big as a pea the other much smaller. The only other thing I can think to tell you is  sometimes when I stretch in the morning I feel a pull in that area.
The lumps you feel are inguinal lymph nodes.... no need to worry about them unless they are enlarging or painful... The pulling sensation is due to stretch if your muscles... if only occasional then it's not significant to be worrisome
