8. Body Pain
Allergies mainly affect the nose because it is the most exposed to foreign substances. If you are experiencing body pain, then you are most likely suffering from a cold, which in turn can cause a fever. Allergies hardly ever reach past the nose or throat, so any aches and pains beyond those areas should be a sign. Fevers are a likely cause of body pain, ergo; you are most likely not suffering from allergies.
