[20F] Experiencing a new rash

Patient Description

A 20-year-old female presents with a new rash on her arm and upper back that appeared three days ago. The rash is described as a little itchy and red, with a distinct border, and is flat without blisters or scales. It has not changed in size or shape since it appeared. The patient has not experienced any fever, joint pains, swelling, or difficulty breathing. She has recently traveled to Egypt for a month but does not recall any specific exposure that could have triggered the rash. The patient started using a new lotion before the appearance of the rash and has no known history of allergic reactions to lotions or other personal care products. No other household members are experiencing similar symptoms.

What might be happening

Based on the information you've provided, here are some possible causes for your rash:

  • Contact Dermatitis: This is a type of skin inflammation that occurs when substances touching your skin cause irritation or an allergic reaction. The new lotion you mentioned could be a possible trigger.

    • Treatment typically involves avoiding the irritant and managing symptoms with creams or ointments prescribed by a doctor.
  • Heat Rash: Given your recent travel to Egypt, a hot climate could have caused a heat rash, also known as miliaria. This happens when sweat ducts become blocked and inflamed.

    • Treatment usually involves cooling the skin and avoiding heat and humidity.
  • Travel-Related Skin Conditions: Traveling can expose you to different environments, insects, and plants that you might not be used to. This can sometimes result in skin reactions.

    • Treatment depends on the specific condition and may involve creams, ointments, or oral medications.

What you can do

  1. Stop using the new lotion you started recently to see if your rash improves.
  2. Keep the rash clean and dry. Avoid scratching it to prevent infection.
  3. Over-the-counter creams and ointments containing hydrocortisone might help reduce itching. However, it's best to consult with a healthcare provider before starting any new medications.
  4. If the rash persists or worsens, seek medical attention. A healthcare provider can provide a more accurate diagnosis and appropriate treatment.

What you should look out for

Seek immediate medical attention if:

  • The rash spreads rapidly or covers a large area of your body.
  • You experience other symptoms such as fever, difficulty breathing, or swelling.
  • The rash becomes painful, or you notice pus or other signs of infection.
