When it comes to understanding scalp conditions, particularly in relation to psoriasis, it's essential to consider both the symptoms and the potential treatments available. Based on your description, it sounds like you are experiencing a persistent itchy area on your scalp near the neck that has lasted for over three years. The presence of white, powdery flakes after scratching could suggest a few different dermatological conditions, including psoriasis, seborrheic dermatitis, or even a fungal infection.

Psoriasis is a chronic autoimmune condition characterized by the rapid growth of skin cells, leading to thick, red patches covered with silvery scales. It can occur anywhere on the body, including the scalp, and is often itchy and uncomfortable. Given that your mother has a history of generalized psoriasis, it is understandable that you are concerned about the possibility of having the same condition.

The fact that the affected area has not expanded significantly over the years might suggest that it is not a typical case of psoriasis, which often presents with more widespread lesions. However, psoriasis can manifest in various forms, including localized patches. The white flakes you mentioned could be indicative of the buildup of dead skin cells, which is common in psoriasis.

In terms of treatment, you mentioned using a foam solution called "易適泡沫液" (likely a topical corticosteroid or medicated shampoo). These treatments can be effective for managing symptoms of psoriasis and other scalp conditions. Topical corticosteroids help reduce inflammation and itching, while medicated shampoos containing ingredients like salicylic acid or coal tar can help remove scales and reduce flaking.

It's important to note that while over-the-counter treatments can provide relief, they may not be sufficient for everyone, especially if the condition is persistent. A healthcare professional, particularly a dermatologist, can provide a more accurate diagnosis and tailored treatment plan. They may recommend stronger topical treatments, phototherapy, or systemic medications if necessary.

If you have had a negative experience with a healthcare provider in the past, it is understandable to feel hesitant about seeking help again. However, it is crucial to prioritize your health and well-being. A different dermatologist may offer a more supportive and understanding approach. They can perform a thorough examination, possibly including a skin biopsy if needed, to determine the exact nature of your condition.

In summary, while your symptoms could potentially align with psoriasis, a definitive diagnosis can only be made through a professional evaluation. Given your family history and the chronic nature of your symptoms, it would be wise to consult a dermatologist who can provide a comprehensive assessment and discuss appropriate treatment options. Don't let past experiences deter you from seeking the care you deserve; your health is paramount, and there are effective treatments available to help manage your condition.
