I'm 23 and I've had a lump in the middle of my back for at least six years (my earliest memory of it). It's never gone more than probably 0.5" wide and has never given me any problems. On 4/20 it grew to over 2" wide (with very noticeable protrusion) and today I noticed a second, smaller (0.25-0.5") lump just above it. The skin around it is tender and feels unattached, giving me small pain when it's leaning against something (bed, chair, wall, when I poke at it, etc.). I wonder if this is something that I can wait out because I can't afford to see a doctor.

Thank you for any help!
