<<Disclaimer: Verify this information before applying it to your situation.>> Does anyone know if there are tests for wheat and dairy 'allergy'. I ate some wheat and dairy recently by accident and started swelling up around the eyes and knees. My joints have been very tender since then. I had this problem some time ago before starting the GF diet and knew I had a big problem with lactose but had not realised it could cause fluid retention like this. Any ideas? Sheila
