Allergies are body reactions to food such as peanut products, particles in the air like pollen or dust that cause constant sneezing, drinks and even smells that cause headaches. Treatment is prescribed once the cause of the allergy is determined by specialized examinations and observation to certain reactive products. These tests are conducted at specialized clinics. Some allergies disappear with age but in the mean time they could be painful or bothersome.
To diminish the effects of allergies try some anti-inflamatory remedies that need no prescription such as Advil in green capsules, Benadryl (causes some dizziness and you should not drive a vehicle under this influence) and Claritin, all found at drugstores.
Serious or constant allergies must be treated at an allergy clinic or by specialist doctor.
