What happens if psoriasis is not treated?

Psoriasis is an inflammatory condition that can follow a waxing and waning course. Without a treatment plan, affected skin may stay red, dry, scaly, itchy, or painful. Scratching and cracking can leave the skin sore and may make it easier for germs to enter. Read about [Dry Skin](/symptoms/dry-skin/) and [Itchy Skin](/symptoms/itchy-skin/) if those symptoms are prominent.

Some people also develop tenderness, stiffness, or swelling in joints. New joint symptoms deserve attention because early assessment can help protect movement. Skin symptoms can occur on different body areas, including the scalp, folds, nails, or widespread patches; untreated symptoms may interfere with sleep, clothing choices, work, and confidence.

Arrange a clinical assessment if plaques are persistent, spreading, cracking, or difficult to live with. Treatment is chosen according to the body area, extent, thickness, symptoms, and other health factors. Options may include [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) or [Vitamin D Analogue Treatment](/treatments/medical-dermatology/vitamin-d-analogue-therapy/). Use moisturiser regularly, avoid picking scales, and keep a note of joint pain or morning stiffness.

Do not stop or restart prescription treatment without checking how it should be used. A clinician can clarify application instructions and review whether another diagnosis or a stronger treatment approach needs consideration.

Seek prompt medical advice for rapidly worsening or widespread redness, painful cracking, pus, fever, or skin that feels hot and increasingly tender. Get urgent help if much of the skin becomes intensely red or starts shedding, or if you feel seriously unwell. Contact a clinician soon for a swollen painful joint, marked stiffness, or reduced movement.

Ask which type of psoriasis is most likely, whether your joints need assessment, how long to try the proposed treatment, and which symptoms should trigger an earlier review. Ask how to protect cracked areas and whether a current medicine could be irritating your skin.
