When my mother eats any shellfish the next day her ears get blood red swells up . She gets a large bump behind her ear, the side of her faceget red, swells and hard and it hurts to touch it. Within 2 to3 days in moves across her eyes and forehead. She doesn't seem to be able to get anyone who can tell her what to or what she call take for it. She gets allergy shots every other week. Is there another kind of doctor she could go see that may specialize in this kind of reaction. She gets get chills and an upset stomach the first two daysi t starts. She is almost 80. She is active and likes to work in her garden and this keeps her down for about 4 to 6 days.
