Hi, It seems that you are having guttate psoriasis. You are having history of tonsillitis. Guttate psoriasis is a type of psoriasis that looks like small, salmon-pink drops on the skin Trigger to the disease is often a streptococcal (bacterial) infection.In your case there is history of tonsillitis. The eruption of the lesions on the skin usually happens few week to few months after the infection. Guttate psoriasis may clear completely following treatment. Sometimes, however, it may become a chronic (lifelong) condition, or worsen to the more common plaque-type psoriasis. There may be pain, secondary infection or severe itching... The disease may heal by itself,if you have mild form of disease. Local steroid and oral antibiotics may be needed. If you have severe guttate psoriasis ,you may take medicines to suppress the body s immune response. These medicines include corticosteroids, cyclosporine, and methotrexate. Sunlight may help your symptoms go away. Be careful not to get sunburn. You may choose to have phototherapy. Phototherapy is a medical procedure in which your skin is carefully exposed to ultraviolet light. Phototherapy may be given alone or after you take a drug that makes the skin sensitive to light. I hope you got my answer. Regards. Dr. Ilyas Patel MD
