The ability to move through the bloodstream of the allergens explains why they can cause symptoms in away areas instead of in the gastrointestinal tract. The symptoms of food allergy may start with symptoms of swelling of the tongue and throat, then numbness, nausea, vomiting, abdominal pain, diarrhea, and may have symptoms in the skin and nasal mucosa.

Allergy  injections help your  body not overreact to the allergens. The injection of the allergens is carried out regularly with each dose later  higher  than previous dose, to reach  the maximum dose. This method is not always effective in everyone and should be monitored by your  doctor regularly.
