Why do I get itchy all the time?

Could be stress.
If your skin is dry, use a good moisturizer until spring.

You likely have cholinergic urticaria induced by heat (translation: itching brought on by heat). Cholinergic urticaria is fairly common, and can occur due to heat, cold, wind, sun exposure or most commonly exercise. You might try an antihistamine to prevent and/or treat your problem.

@shilolo: great answer! Guess that’s why you’re a doctor and I’m a nurse.

@cdwccrn Who are you kidding. Nurses know more than doctors.

Besides, according to another (unnamed) user, I’m not really a doctor, I’m just faking it.

< < after scouring the fluther-net a bit (thanks new, improved search!), I’m wondering if (unnamed) user is a certain fan of the Rocky Horror Picture Show?

@robmandu Good guess, but, no.

@shilolo: AHHHHH!! You just answered a question I had long wondered about. I tend to get really itchy after I exercise – particularly snowshoeing or x-c skiing. I assumed it was just a histamine response of some sort. Thank you!

@figbash. It sounds like you have two potential triggers, cold and exercise. You were right to suspect histamine. If it is bothersome, an antihistamine like benadryl or a non-sedating brand can help.

@shilolo: Thank you!!!! As Breefield can probably attest, that itch is one that you just cannot scratch no matter how long you try . . .

could also be a hypoglycemia.

This is still happening to me, and the source is becoming less pin-point-able, and the frequency is far more offten. I need to decide if it’s worth a trip to a dermatologist or not…
