I have been dealing with psoriasis in my legs for a few months, (just a couple of spots) treating with coconut oil and tea tree oil. It all got better, then a flare up with lots of swelling in my left lower leg and fluid oosing out through the skin. Now blotches on the other leg, sparce itchy spots on my back, arms and neck (mostly in the evenings), and today my face is swelling up and showing blotches. Advise??
