Psoriasis typically manifests itself as patches of the skin that are dry, red, and covered in silver scales. There are different types of this skin condition and each may have its distinct symptoms.
However, the most common symptoms of psoriasis include:

Common Symptoms of Psoriasis:

• Red, inflamed patches
• Painful, swollen joints
• Thick, pitted nails
• Burning and itching sensation around the areas affected
• Soreness around the patches
• Dry skin that may break and bleed
• Silver-white scales

Diagnosis of Psoriasis:

• Physical examination: Your doctor can suspect or diagnose psoriasis by examining your scalp, skin, and nails. Since psoriasis can also be genetically inherited, the doctor may also check your family’s medical history.
• Biopsy: Further tests may be required as psoriasis resembles other skin diseases, such as eczema. Your doctor takes a small piece of skin and sends it to a pathologist for further examination.
• X-rays and blood tests: For patients with joint symptoms, such as painful and swollen joints, blood tests and x-rays are vital to rule out other forms of arthritis.
