Dear God my friend I am there with you. You need to see an allergist, most of the time they may not find anything that you are actually allergic to but can give you heavy duty meds, or a steroid to help calm down your immune system. I would def call an allergist tomorrow, or get a referall for one from your doctor. The OTC shit won't do too much and is expensive. I am currently suffering from them now too. Mine are chronic, and I was hive free for months and they appeared recently. They put me on a combo of 4 meds which worked for a day, but then i went out and drank one night and i think it agitated my hives more. Let me know how it goes. In the mean time

I'd try zurtec or allegra i've used both and been prescribed both high duty versions i dont know if benadryl even does shit.

1) wash your sheets with a non-allergetic or w/e wash just in case
2) You can try cool ice to calm them
3) Usually they have cortisol or over teh counter ich cream u can get
4) avoid scented lotions and sprays
5) try to make of list of anything different u may have done or have been doing to bring them on
6) if they are in fact stress induced, then u need to trick your body into thinking ur relaxed. i know this is hard but i deep breathe close my eyes, tell my something good thoughts, curl up in bed, and listen to soothing music, and drink water, or a bath.

good luck, let me know if u need to chat more

Three things I do to tell if it's anxiety hives, or reaction acute anxiety hives~
a) itching sensation level and duration of level=action of movement
b) location and spread of itching sensation=physical symptom change position
c)keep a timeline of itching sensation=origin of anxiety physical symptom and often a fast natural solution

Where it is resting anxiety hives, I have found that keeping it comfortable often takes distracting the sensation, like a massage on the scalp, rubbing the feet, and getting something to drink.

Where it is acute anxiety hives, moving around often distracts the hives from spreading, and gives fast natural relief to the acute physical symptoms of itching.

When I am having the itching due to sinus reaction, I have to massage my nose, my eyebrow and around my eyes to get the sensation to ease off.

Best wishes finding what works for you.

This happened to me.. I saw both a dermatologist and then was referred to an allergist.
Basically this is what I was told. I had contact dermatitis which was a reaction to an allergin. This made me feel itchy and I did get a few hives but the most bothersome was the itching. I initially thought that somehow I got body lice and became very stressed. I took hot showers, used bleach in laundry and sterilized everything. When i saw the dermatologist he said that I was actually making things worse and did not have any bugs or skin bacteria. He explained that the hot showers just agrivated things and now my skin had become super sensative to everything. The stress I felt even made the situation worse. It took a few weeks but was given a nivea type cream with no perfumes, had to use fragrance free detergents, use dove sensitive skin body wash, have lukewarm showers, not to dye hair or use make-up.
I later learned I was allergic to latex. Waistband, bras, underwear, bedding and even feminine pads often have latex in them. I still get flare-ups but not as bad.
