[33F] With blister-like bumps and numb fingertips

What might be happening

Based on the information you've provided, here are some possible conditions:

• Eczema (Dermatitis): This is a condition that makes your skin red and itchy. It's common in children but can occur at any age. Eczema is long-lasting (chronic) and tends to flare periodically. It may be accompanied by asthma or hay fever. Treatment usually involves moisturizing your skin regularly and using medications to control symptoms.
• Psoriasis: This is a skin disorder that causes skin cells to multiply up to 10 times faster than normal. This makes the skin build up into bumpy red patches covered with white scales. They can grow anywhere, but most appear on the scalp, elbows, knees, and lower back. Treatment may include creams, light therapy, and medication.
• Cutaneous Vasculitis: This refers to inflammation of the blood vessels in the skin. Symptoms can include red or purple discolorations, blister-like lesions, and ulcerations. Treatment typically involves corticosteroids or other immunosuppressive medications.
• Pyoderma Gangrenosum: This is a rare condition that causes large, painful sores (ulcers) to develop on your skin, most often on your legs. The exact cause is unknown, but it's thought to be a reaction to an illness, injury, or certain medications. Treatment usually involves corticosteroids or other anti-inflammatory drugs.

What you can do

1. Keep the area clean and dry to prevent infection.
2. Avoid scratching or picking at the lesions, as this can worsen the condition and potentially lead to infection.
3. Apply a moisturizer to your skin regularly to help alleviate dryness and itching.
4. Over-the-counter creams and ointments containing hydrocortisone may help reduce inflammation and itching. However, these should not be used for a prolonged period without consulting a healthcare provider.
5. Seek medical attention. Your healthcare provider can provide a definitive diagnosis and appropriate treatment.

What you should look out for

• If the lesions become more painful, larger, or start spreading rapidly, seek immediate medical attention.
• If you develop a fever, chills, or feel generally unwell, these could be signs of an infection and you should seek medical attention.
• If you notice any changes in the color, size, or shape of the lesions, or if they start bleeding, these could be signs of a more serious condition and you should seek medical attention.
