[20F] With a spreading rash on leg

What might be happening

Based on the information you've provided, possible causes for your symptoms include:

• Contact Dermatitis: This is a type of skin inflammation that occurs when substances touching your skin cause irritation or an allergic reaction. The red, itchy rash isn't contagious or life-threatening, but it can be very uncomfortable.

  • Treatment typically involves avoiding the irritants, applying anti-itch creams, and using cool compresses to soothe the skin.

• Hives (Urticaria): These are red, itchy welts that result from a skin reaction. The welts may appear anywhere on the skin and can be as small as a pen tip or as large as a dinner plate. Hives can be triggered by many situations and substances, including heat, exercise and stress.

  • Treatment for hives can involve antihistamines to control the itching.

• Insect Bites: Certain insects can cause a rash through bites or stings. Many insects, such as mosquitoes, mites, and spiders, can cause a reaction in the skin with redness, swelling, itching, and pain.

  • Treatment usually involves washing the area with soap and water, applying a cold compress, and using an over-the-counter treatment to relieve itching and swelling.

Please note that this is not an exhaustive list and other conditions could also be responsible for your symptoms.

What you can do

1. Avoid scratching the rash or bumps, as this can lead to further inflammation and possible infection.
2. Apply a cool, damp cloth to the area to help soothe the skin and reduce inflammation.
3. Over-the-counter creams and ointments can help to relieve itching and redness. Look for products containing hydrocortisone for best results.
4. If the rash continues to spread or becomes more uncomfortable, make an appointment to see your healthcare provider.

What you should look out for

• If the rash or bumps become painful or start to ooze
• If you develop a fever or other symptoms such as joint pain or a sore throat
• If the rash doesn't improve after a week of home treatment
