[50F] With sudden rash and fatigue

What might be happening

Based on your symptoms and medical history, here are some possibilities:

1. Allergic Reaction or Contact Dermatitis: The sudden appearance of a rash under your breasts, especially after wearing a new bra, suggests a possible allergic reaction or contact dermatitis. This can occur when your skin comes into contact with an irritant or allergen, such as certain fabrics or chemicals in clothing. The heat and itchiness are common symptoms, and the bruised appearance could be due to inflammation.

2. Lupus Flare: Given your history of lupus, it's possible that your symptoms, including fatigue, headaches, and rash, could be related to a lupus flare. Lupus can cause a variety of symptoms, including skin rashes, fatigue, and headaches.

3. Viral Infection: The combination of fatigue, headaches, nausea, and a transient fever could indicate a viral infection. Viral infections can sometimes cause skin rashes as well.

Typical treatments or testing might include:

• For contact dermatitis, avoiding the irritant and using topical corticosteroids or antihistamines can help.
• For lupus, managing flares often involves medications like corticosteroids or immunosuppressants.
• If a viral infection is suspected, supportive care such as rest, hydration, and over-the-counter pain relievers may be recommended.

What you can do

Rash and Itchiness:

• Avoid wearing the new bra or any clothing that might irritate the area.
• Continue using over-the-counter antihistamines like Benadryl to help with itching.
• Apply a cool compress to the rash to reduce heat and discomfort.
• If the rash worsens or doesn't improve, consider seeing a healthcare provider for further evaluation.

Fatigue and Headaches:

• Ensure you are getting adequate rest and staying hydrated.
• Try to maintain a regular sleep schedule to help manage fatigue.
• Over-the-counter pain relievers like acetaminophen or ibuprofen can help with headaches, but use them as directed.
• If headaches become severe or persistent, seek medical advice.

General Health:

• Given your medical history, it's important to manage your chronic conditions. If possible, try to reconnect with a healthcare provider to discuss your symptoms and any necessary medications.
• Use MDandMe to journal your symptoms, track progress, and share insights with your healthcare provider when you can.

What you should look out for

• If you experience difficulty breathing, swelling of the face or throat, or a rapid spread of the rash, seek emergency medical care as these could be signs of a severe allergic reaction.
• Monitor for any new or worsening symptoms, such as increased fatigue, persistent fever, or joint pain, which could indicate a lupus flare or other underlying condition.
• If your symptoms do not improve or you have concerns about your health, consider seeking medical attention for a thorough evaluation.
