Ive had a small mole on my back for years, that began to raise so i went to my doctor. He assured me i had nothing to worry about so i didnt remove it. Since then ive used tanning beds alot, and although i stopped along time ago, the mole on my back is raised alot and just randomly started stinging. Even my loose shirt grazing it is hurting. Ive also noticed other moles have become larger and a flat pink colored mole on the side of my face. Are these symptoms of melanoma?
