Another reason it's hard to determine if you have a radon issue in your home is because the symptoms are similar to other illnesses and diseases. Symptoms can include hoarseness, a persistent cough, wheezing, chest pain, shortness of breath, frequent lung infections, fatigue, weight loss, coughing up blood, and more. If you experience any of these symptoms, especially as a chronic condition, besides contacting your doctor, consider testing the radon levels in your home.
