Is that a snake in my leg??

Today I was sitting outside after my workout and noticed a LONG line up the inner part of my thigh (from my knee to about mid thigh area on the inside of my leg). My first reaction was..OMG what is that could it be a tendon??!! Worried I may be injuring myself from my walk/job regime I had my husband feel it tonight and he LAUGHED at me so hard he almost fell down. He looked at me when he stopped laughing and said "baby, that's your gracilis muscle". I have to admit I was a bit embarassed to be worried BUT so happy I can feel a muscle that is so small in both my legs now!! SOOO its not an injury but a possitive response to my workouts. I don't remember EVER being able to feel that muscle even when I was 114 lbs in my early twenties. That is my NSV story for the day
