Ive had this thing on the inside of my leg near my private for over 5 years. it is underneath the skin and when ever i touch it ,it feels like its a rubber band. i think it might be a blood vessle. i feel some pressure there like it is pulling on what ever it is attached to. kinda like the vessle isnt long enough for my leg. it causes my leg to go slightly numb sometimes. just wondering would anyone know what this might be? or does anyone else have this also? if you need more info. just let me know. il explain the best i can.
