Hi, I am a 20 year old male, 5'7, weighing 63kg. No medical history, relatively healthy, exercise 4 times a week. I've got a lump on my back (around level of T12/L1) from about 4 years ago when I raced gokarts. The seat was a bit big for me so i slid left to right in it. It would give me what seemed like a welt on my back but now has become what seems to be permanant (~3cm diameter). I havnt raced gokarts since, and it isnt decreasing in size/nor increasing. I was wondering what it could be??? It does not cause discomfort, but is to the left of my spine, superficial to erector spinae muscle.
Any help would be very much appreciated, can it be removed easily without scarring?
Thankyou
