I like book titles with double meanings. My first published book was titled, Proof. There were two types of proof the heroine needed. Proof to convict her assailant of his horrific crimes and proof of God in her life.
- Eyes: Irritation, redness, burning, inflammation and even blindness
- Skin: Itchy redness that is replaced with yellow blister
- Respiratory system: Runny or bloody nose, sneezing, hoarse throat, shortness of breath, coughing, sinus pain
- Digestive system: abdominal pain, diarrhea, fever, nausea and vomiting
