An allergy is a sensitivity to a substance which does not normally cause people any problems.
What to look for:
Sneezing, wheezing, nasal congestion, and coughing indicate asthma, or drug or respiratory allergies.
Itchy eyes, mouth, and throat are symptoms of respiratory allergies.
Stomach ache, frequent indigestion, and heartburn and diarrhoea are signs of food sensitivities.
- Irritated, itchy, reddening, or swelling skin is associated with drug, food, and insect sting allergies.
- Stiffness, pain, and swelling of joints may indicate food or drug allergies.
Allergies come in a variety of forms and vary in severity from mildly bothersome to life-threatening.
