Understanding foot skin issues can be quite complex, as various symptoms may indicate different underlying conditions. Based on the information provided, it seems you are experiencing some concerning symptoms that have led to a diagnosis of cellulitis (蜂窩性組織炎). However, you are skeptical about this diagnosis, which is understandable given the variety of foot skin conditions that can occur.

Cellulitis is a bacterial skin infection that typically presents with redness, swelling, warmth, and pain in the affected area. It often occurs when bacteria enter through a break in the skin. Symptoms can escalate quickly, leading to systemic issues if not treated promptly. However, if your symptoms do not align with typical cellulitis presentations, it may be worth exploring other possibilities.

Common foot skin issues include:
1. Fungal Infections: Conditions like athlete's foot (tinea pedis) can cause itching, peeling, and redness between the toes. Fungal infections can sometimes lead to secondary bacterial infections, which might mimic cellulitis.

2. Eczema or Dermatitis: These conditions can cause redness, itching, and sometimes blistering. They can be triggered by irritants, allergens, or even excessive sweating.

3. Psoriasis: This chronic skin condition can affect the feet, leading to red patches covered with thick, silvery scales. It can be itchy and painful.

4. Contact Dermatitis: This occurs when the skin reacts to a substance it has come into contact with, leading to redness, itching, and sometimes blisters.

5. Blisters: These can form due to friction from shoes or excessive moisture. If they become infected, they can lead to more serious conditions.

6. Vascular Issues: Poor circulation can lead to skin changes, including discoloration and ulceration, particularly in individuals with diabetes or peripheral artery disease.

7. Neuropathy: Conditions like diabetes can lead to nerve damage, resulting in a lack of sensation in the feet. This can lead to unnoticed injuries that may become infected.

Given your situation, if the diagnosis of cellulitis does not seem to fit, it is crucial to seek a second opinion from a dermatologist or a specialist in infectious diseases. They can provide a thorough examination and possibly perform diagnostic tests, such as a skin scraping or culture, to determine the exact cause of your symptoms.

In the meantime, here are some general recommendations for managing foot skin issues:
- Keep the Area Clean and Dry: Proper hygiene is essential. Wash your feet daily and ensure they are thoroughly dried, especially between the toes.

- Avoid Irritants: If you suspect a reaction to a product (like soap or lotion), discontinue use and observe if symptoms improve.

- Moisturize: If dryness is an issue, use a fragrance-free moisturizer to keep the skin hydrated.

- Wear Appropriate Footwear: Choose shoes that fit well and allow your feet to breathe. Avoid tight-fitting shoes that can cause friction and blisters.

- Consult a Specialist: If symptoms persist or worsen, seeing a healthcare provider is essential for proper diagnosis and treatment.

In conclusion, while cellulitis is a serious condition, it is important to consider other potential diagnoses based on your symptoms. A thorough evaluation by a healthcare professional will help clarify the situation and guide appropriate treatment.
