<s>[INST] I have what has sometimes been diagnosed and psoriasis and sometimes as i am not sure what it is. It is a form of psoriasis. I usually have to take an antibiotic to keep infection down. It is not helping at this time. My skin is very inflamed and itchy and i feel like i am having an alergic reaction on the inside and outside of my body. I am unsure what to do at this point. I don t usually itch with my psoriasis as much as i have this week. I am wondering if i need to see a Dr. to get a steriod shot or something. [/INST] Hi. I think probably you may be having allergic dermatitis along with psoriasis.... Psoriasis is a chronic relapsing and autoimmune disease. You may be having scaly plaques on various parts of the body, scaly lesions on the scalp. Exact cause is not known. Genetic tendency, autoimmunity, stress, Chat Doctor. .etc. may be responsible for precipitation and exacerbation of psoriasis. You said that from last few days you have inflamed skin with itching...that would be due to allergy. You consult dermatologist for firm diagnosis and treatment. I usually recommend cap accretion 10 mg twice a day along with methotrexate 15 mg weekly in three decided doses 12 hourly...for psoriasis. This may be taken for long time till good response. Blood tests may be done to monitor the treatment. For itching, you may take antihistamines like levocetirizine. If needed, steroid may be taken for short period in tampering dose. Antibiotic course may be considered, if there is secondary infection. You may apply mild steroid cream or calcitriol point on the lesions on the psoriasis lesions. You may apply moisturizer to improve the skin texture. Furthermore, you should avoid soap bath for few weeks. And you should free of stress and worries as that might worsen psoriasis. For inflamed skin, you may apply antibiotic cream. You might get good result. I hope you got my answer. Thanks. </s>
