  • Red patches
  • Inflammed skin
  • Sore and dry patches
  • Painful joints

Treatment for psoriasis

Dr. Nandini said, "Psoriasis is diagnosed by a biopsy first and then specific treatment is done by the doctor. No hospital admission is required for this skin condition, unless it is erythrodermic psoriasis. Psosriasis can be dealt with at home, with remedies and medications. For acute guttate, only antibiotics are prescribed by the doctor as it is caused by streptococcal bacterial infection." On the other hand, in psoriatic plaques, there are dry whitish silver scales and dryness, for which the dermatologist might advice steroids or make you apply emollients (moisturizers). Moisturizers have to be used, otherwise the psoriasis might become active. Doctors give oral therapy, biologics and photo therapy too for this skin disease.
