not at all. I appreciate the detailed questions.

1. history and occurrence

i'm a gamer who tries to stay fit. i am not precisely sure when it happened but one day when I was exercising I did feel a very different almost twisting pain near that area after intense cardio work out.

although I did not check the area because I assumed I merely pulled a muscle.

only to notice days later I have a horizontal indentation between the hip bone and thigh on the left side.

2. not long a few days at most. it's about 2 maybe 3 inches going horizontal. length wise not long at all.

3. it's below the hip bone but above most of the thigh. I did research on the anatomic location and it's either the Iliotibial band or glutes medias. possibly tensor fasciae latae.

the muscle in the location only (or tendon?) Is gone until I flex it then it magically reappears temporarily.

4. no surgeries ever.
