I have been suffering with patches of itching bumps that form liquid, sometimes bleed then scab almost repeatedly. At times I have even felt ill like head & neck pain after scratching the bumps repeatedly. Someone told me I may have an allergy to hair dyes so I switched to henna dye only with the same reaction. My Dermatologist told me it may be a dermatitis but I should seek an allergist which I have not yet. This problem has been going on now for almost a year. Please advise as what it may be and which medical Doctor I should seek? I would appreciate a professional opinion as I m at my wits end!
