[37M] With severe itching upon sweating or getting wet

What might be happening

Based on the information you have provided, here are some possible explanations for your symptoms:

• Cholinergic Urticaria: This is a type of hives that occurs in response to sweating, heat, or stress. It can cause severe itching without a visible rash. The itching usually starts a few minutes after sweating begins and can last for an hour or more.

  • Treatment: This condition is typically managed with antihistamines to reduce itching and prevent hives. Avoiding known triggers, such as hot showers or intense exercise, can also help.

• Aquagenic Pruritus: This condition causes intense itching after contact with water, without any visible skin changes. It can be triggered by sweating, bathing, or swimming.

  • Treatment: Antihistamines and topical treatments may help alleviate symptoms. Moisturizing the skin and using lukewarm water instead of hot water can also be beneficial.

• Eczema (Atopic Dermatitis): Although you mentioned no visible rash, eczema can sometimes present as severe itching without an obvious rash, especially in its early stages.

  • Treatment: Moisturizers, topical corticosteroids, and avoiding known irritants can help manage symptoms.

What you can do

While you should consult a healthcare professional for a formal diagnosis and treatment plan, here are some steps you can take to manage your symptoms in the meantime:

1. Avoid Triggers: Try to avoid activities that cause you to sweat excessively or get wet. If you need to exercise, consider doing so in a cool environment.
2. Use Cold Air: Since cold air helps relieve your itching, consider using a fan or air conditioning to cool down quickly after sweating.
3. Moisturize: Apply a good quality moisturizer to your skin to help maintain its barrier function.
4. Lukewarm Water: Use lukewarm water instead of hot water when bathing or showering to minimize itching.
5. Over-the-Counter Antihistamines: You may find relief from over-the-counter antihistamines like cetirizine (Zyrtec) or loratadine (Claritin).

What you should look out for

Seek medical attention if you experience any of the following:

• Severe or Worsening Symptoms: If your itching becomes unbearable or starts to interfere significantly with your daily life.
• New Symptoms: Development of a rash, hives, or any other new symptoms.
• Signs of Infection: Redness, swelling, or warmth in the affected areas, which could indicate an infection.
