hi I have guttate psoriasis from a troat infection, and was on antibiotics and steriods for a week, and also using betnovate gel for the past two weeks, the psoriasis completely cleared in about a week and a half which was great but in the last 3-4 days it has come back even more agressively, the doc say if it hasn t gone in 4 weeks that I could get light treatment, what do you recommend from reading this? thank you for your response!
