I had all blood tests done, cost me a fortune since I have no medical due to lack of income. The allergist said it was related with my rheumatoid arthritis as a rare symptom that just happens and to see my rheummy to get help from her.
With the rheumatologist, I have had all kinds of tests done from stool samples, to blood tests for everything from rheumatoid to cancers, infections, hep a b and c etc. I have been poked for blood so many times I call myself the human pin cushion. :)
The one thing that hurts the most is sorbitol. It's a sweetener they like to put in foods to lower their calorie number from trident gum to all sorts of drinks and foods. When I eat it, I get rappid pain so bad I can't walk, sit up, roll over in bed etc. someone has to do it for me.
Things that hurt me allergy wise the most are dust, molds, sorbitol, anything dairy except cheddar cheese (weird hungh), any artificial sugar makes me hurt like sorbitol but not as bad and other goodies made of chemical that i either breathe in or digest. I also can't be near new paint, new carpeting and if you have a brand new home, i can't visit for at least four years. My chemical allergies are huge.
Sometimes you think you just can't win.
