Causes of a sore throat
A sore throat is often a sign that you may have an infection in the area, but there are other things that can irritate the throat, causing reddening and swelling. These include cigarette smoke, a polluted environment, voice strain or even changes in air temperature.
Although there are lots of symptoms of a sore throat from that nasty raspiness, pain when swallowing to a sudden husky voice - there are lots of medications that can help soothe the pain, and that can keep on working, even after the lozenge has gone. Look up Strepsils in my reference library to find a suitable remedy for you.
