Hi. Thanks for posting your concern at HCM I would keep a possibility of leukonychia of nails which is usually due to trauma of the nail ned/nail matirix. They would resolve as the nail grows and require no intervention. White flaky areas and lumps on the scalp along with itching and bleeding on scratching is most likely due to Seborrhoetc dermatitis of the scalp with secondary folliculitis(bacterial infection). I usually advice my patients to use an antidandruff shampoo thrice weekly. Ketoconazole based shampoo, is an antidandruff shampoo which is available OTC and can be tried. I would have also advised a week of oral antibiotic for the lumps/secondary bacterial infection. I would advice that you seek an ophthalmologist consultation regarding your eyesight. take care regards
