Hives After Sweating?3 Details to Bring to a Visit

If itching makes you cut a walk short or hesitate before a hot shower, describe the interrupted activity when you seek care. The clinician needs to know what happens around the rash as well as what it looks like.

Three details to record

1. What happened before the bumps? Note exercise, heat, a bath, spicy food or stress if relevant. These are described triggers, but your account should include what you noticed without deciding the diagnosis yourself.¹
2. How quickly did they appear and fade? This condition can cause small, itchy or burning raised bumps that start within minutes of a trigger and are transient. Record the timing and take a photo if you can do so safely.¹
3. Did anything happen beyond the skin? Tell the clinician about breathing symptoms, swelling, faintness or abdominal symptoms. Cholinergic urticaria can rarely involve a systemic reaction.¹

Know when to seek immediate help

Call 911 or your local emergency number for sudden throat or tongue swelling, trouble breathing or swallowing, or collapse. These can be signs of a severe allergic reaction. If you have a prescribed adrenaline auto-injector, use it as instructed while getting emergency help.²

For a routine visit, include the activities you have started avoiding and the questions you want answered about them. Ask how to approach those activities while the cause is being assessed. Do not recreate a severe episode to get a better photograph.

Arms Up includes a Fresh Log and a visit script. Use them to organize the timing, triggers and questions for your appointment. See the book.
