the flare up of psoriatic lesions after stopping the steroid
is called "rebound effect". since all the lesions have come back with increased intensity, you need to make a fresh start . depending on the area and severity the treatment modality would be decided. if the area of involvement is not so widespread, you can start using topical formulations, ie. steroid creams along with coaltar preparation. keep on moisturizing your lesions well in between the medicated creams. try to avoid any stress
and sun exposure will benefit you as well.
