My son had severe food allergies and they didn't show up with a blood test. I knew he was allergic because his symptoms would clear up without the food but get so bad with it. My chiropractor did muscle testing and the allergy did show up. I've had two friends whose children had severe allergies but the blood test and skin test was normal. Either you're allergic to something that wasn't tested or else the test doesn't work for you. Find a chiropractor or homeopathic that does allergy testing (if you don't mind alternative doctors.) You might be able to find a MD or DO that does a test different than blood or skin tests.. (My homeopathic is a MD) Good luck!!
