Thank you for submitting your question regarding Tyson. Poor guy! He does look uncomfortable. I would continue everything you are doing treatment wise. Is the benzoyl peroxide cream a shampoo? If not, I would a shampoo as bathing can help. This helps to flush the mites out of the hair follicles. He will likely need an antibiotic as I suspect that he has developed a secondary bacterial infection. This is common. This should help the skin heal as the mites are treated. Good luck!
