@hopeful33250 I initially thought the growth was a wart! I. Went to my Dermatologist who stated it was was not a wart! That I needed to see an upper exterminities Orthopedic Doctor. The growth that started out as a pimple grew rapidly and started to change color, bleed and hurt! I have no idea where it came from! I'am not out in the sun much! But, I do drive with left hand at the 12:00o'clock position! Also my immune system was down do 13 weeks of RSV!
