Re: Allergy Testing~ how accurate?
Do you go tanning, in the sun or in a tanning bed? Do you go swimming? Did anything change recently(you may have to call about this) in your city's water system(IE: did they change chemicals in it?)?
Usually intense itching all over(does it wake you up at nite?) means you are being immersed in something, like a tanning bed's UV rays/ sun's UV rays, or heavily chlorinated/water with a lot of chemicals in it or change of. And usually steroid creams don't help much.
I don't know why they are sending you for allergy testing, in this kind of situation, this can be pretty dangerous to the person with skin allergies.. it can cause a whole load of rashes that are tricky to treat. Generally it's best to wait until you have calmed down.
you may need to do a lot of trial & error, that's my best suggestion as you will find the allergy testing will only make things worse. My advice to you is try to remove one thing you suspect is triggering the itching at a time, and see if that helps(use a different lotion, brand of makeup, detergent, soap, shampoo, cleaning solution, etc, etc,). Do you have a cleaning lady? Is it possible if not, to get one for a day & have them scrub your place clean of dust? Dust is a HUGE trigger for me.. you may want to consider wall to wall hardwood floors & air purifiers & filters & allergen proof bed encasings.
Also look for things in your diet that have felt funny or that you have done differently.
Try changing your antihistamines.. sometimes different ones will work better than others. You may need a short, low dose burst of prednisone. In TINY amounts, it will probably do the trick. Good luck, let me know if you need anymore advice.. i'm the skin allergies guru over here=)
