Wow... It's really hard to get a doctor to believe you regarding HIT when you look like you're having an allergic reaction like hives. I live in Washington State in the USA. I had been eating processed frozen dinner/lunches, lots of fresh spinich salads and yogurt... all the foods that we think are good for us, but are loaded with histimines. My back was completely covered with this insane, itchy rash that would bleed horribly when I'd scratch it. The back of my arms were covered as well. I was going insane and put up with this for almost a year. I had gone to 3 general docs and 2 specialists,all of whom just scratched their own heads and would give me a cortizone injection.

I accidently found some information on line about HIT and saw photos of the same rash I had! Finally! I did my OWN diet illimination test for 4 weeks and found how what was making me go crazy with this horrible rash(and headaches for years). I take antihistimines now and stay away from the foods that are loaded with H. I actually have scars on my arms. Here's a great test that I discovered the other day. I had a G&T (gin and tonic) and my arms started the itch about 8 hours later. Whoa! Get the word out! HIT is a very real and hard to diagnose problem. Don't give up and always go to a doctor and educate them on what you've found. Mine finally listened to me. I had a huge allergy test and I wasn't allergic to ANYTHING AT ALL! Of course I was given a histimine injection under the skin so they could see if I'd have a reaction. Oh boy! Did I ever! My arm swelled up and got bright red.

This is tricky stuff alright. Take care everyone. It gets better when you pay attention to what you're eating and avoiding the foods that are loaded with H. It's not the end of the world
