[25M] Experiencing sudden onset of hives and swelling

What might be happening

Based on the information you've provided, possible diagnoses include:

• Urticaria (Hives): This is a common skin reaction that causes itchy, raised welts, which can appear anywhere on the body. Urticaria can be triggered by many things, including certain foods, medications, or other irritants. Even though you don't have known allergies, it's possible to develop new allergies or reactions.

  • Treatment typically involves antihistamines to reduce itching and inflammation. Avoiding known triggers is also important.

• Angioedema: This is a related condition that causes swelling beneath the skin, often around the eyes and lips. In your case, it could be causing your swollen fingers and eyelids.

  • Treatment usually involves medications to control the swelling and itching.

• Contact Dermatitis: This is a skin reaction caused by contact with certain substances. The substances could be something new in your environment, or something you've been in contact with for a long time.

  • Treatment involves avoiding the substance that's causing the reaction. Corticosteroid creams can help reduce inflammation and itching.

What you can do

1. Seek immediate medical attention if your symptoms worsen, if the hives or swelling spread to other parts of your body, or if you have difficulty breathing.
2. Over-the-counter antihistamines may help with the itching and swelling, but it's important to follow the package instructions.
3. Try to identify any new substances you've come into contact with recently, as they may be causing your symptoms. This could include new soaps, detergents, foods, or plants.

What you should look out for

• Difficulty breathing or swallowing, which could indicate a severe allergic reaction.
• Hives or swelling that spread to other parts of your body.
• Symptoms that don't improve with over-the-counter treatments.
