Burn Like Marks: You have multiple dark patches on arm and looks like a burn these might be.. I) lichen planus pigmentosus or ii) fixed drug eruption or iii) tinea versicolor or iv) para psoriasis or v) tinea corporis but rare chance of being an acanthosis nigricans it would be a wise decision to confirm your diagnosis first then manage it. You can consult a dermatologist.
