[20M] Experiencing upper body itching and sharp sensations triggered by heat

What might be happening

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

• Cholinergic Urticaria: This is a type of hives that is triggered by a rise in body temperature, such as when you're in a heated room or under warm clothes. It's characterized by itching and a sharp sensation without pain, but it typically also involves the appearance of small hives or bumps, which you didn't mention.

  • Treatment typically involves avoiding triggers, such as heat and stress, and taking antihistamines.

• Heat Rash (Prickly Heat): This condition occurs when sweat ducts become blocked and sweat can't get to the surface of the skin. Instead, it gets trapped beneath the skin's surface, causing a rash and itching.

  • Treatment typically involves cooling the skin and avoiding heat and humidity.

• Dermatographism: This is a type of urticaria where scratching or rubbing the skin causes redness, swelling, and itching. It's not clear from your description whether this might be the case.

  • Treatment typically involves avoiding triggers and taking antihistamines.

Please note that these are only possibilities and not a definitive diagnosis.

What you can do

1. Try to avoid triggers such as heat and stress.
2. Keep your skin cool and dry.
3. Over-the-counter antihistamines may help with the itching, but you should consult a healthcare professional before starting any new medication.
4. Wear loose, light clothing that allows your skin to breathe.

What you should look out for

• If your symptoms worsen or you develop new symptoms, such as hives, swelling, or difficulty breathing, seek medical attention immediately.
• If your symptoms persist despite your efforts to avoid triggers and keep your skin cool, you should consult a healthcare professional.
