Trobinson - you rant away!! It really helps me to read and/or write on this board knowing there are people who really, really understand me.
One of my triggers is any kind of food coloring. It will make me sick all over, and cause me to have a kidney/bladder infection. Food coloring is in so many things you don't even think about. Might try being aware of that.
For the burning and/or itching, I will use Aloe Vera gel (pretty thick layer) all over arms, hands, feet, legs chest, - anywhere that needs it, and turn the ceiling fan on high. Lay back in the recliner and shut my eyes - kinda feels like I'm on the North Pole with a helicopter sitting next to me!!
Of course, this probably wouldn't be a good idea for the work place. But, if it gets bad enough........shed your clothes.....smear the gel....and face all the fans toward your chair. Be sure to keep your eyes closed, cause no one else in the office will be able to shut theirs'!!!
But, I bet they might take your pain more seriously........or then, again, might just send you home for the day......either way, it's a win/win..........I'm just sayin'.........
