You should consult your doctor or a dermatologist to determine whether your symptoms are caused by psoriasis or a similar condition, such as eczema or an allergic reaction. Your doctor may suggest using fragrance-free emollients to hydrate the skin and reduce scaling, or prescribe a mild topical steroid to manage inflammation and relieve itching. It is also essential to keep the skin well moisturised and avoid known triggers such as harsh soaps, stress, and allergens.

A random blood sugar level of 175 suggests impaired sugar control, so reduce sugary foods, eat balanced meals, exercise regularly, and arrange fasting and HbA1c tests with your doctor. Skin allergies may worsen with high sugar intake, so keep the skin moisturised, avoid known triggers, and use prescribed antihistamines or creams as advised by your doctor.
