Hi, I had tonsillitis nearly 2 weeks ago and at the weekend I developed guttate psoriasis. I am covered from head to tow in spots an it is so it itchy. The doctor has prescribed sown steroid tablets and cream but has said it could last for 3 months. Has anybody had this before and did it last that long. Thankfully it is not on my face but everywhere else is covered so it's quite embarrassing going out!
