I'm a teacher and work 8 hrs a day, that is 8 hrs of speaking a day! I've heard that larynx cancer is the most common cancer among teachers and I'm afraid I might get one. I'm always clearing my throat and sometimes when I speak a lot I feel like someone has scratched my throat. Any suggestions? If you have had it for along time like that i would see a doctor, sounds like some damage has been done. Our thoats do need a rest.I have 4 children and talk none stop most 24 hours as well, but dont have that trouble.May-be you have a fish or chicken bone stuck some where to, i have heard of things being stuck or scracthing the thoat like that. Please go see a doctor. Try using some sort of soothing throat lozenges as well as using a throat spray at frequent intervals throught your day. If your symptons persist I urge you to see a doctor for diagnosis and treatment. |
