Hello, Working around irritants can cause inflammation to your throat. Definite symptoms would include a dry, scratchy throat that would promote a chronic cough. Having a discharge can indicate more severe damage resulting in tissue that is infected. Chemical burns can cause ulcerations. Do what you can to avoid all irritants. Consider wearing a mask. Limit your diet to avoid very acidic foods. keep well hydrated. Do you have any gastric disturbances? Acid reflux can irritate the throat and medication can be prescribed. Consider visiting your doctor for a clinical exam and possible endoscopy to view your esophagus. Other diagnosis concerns include polyps, rumors or cancerous growths. Thank you for your inquiry. I hope my suggestions are helpful and you feel better soon.
