How do i clear my throat? about a month ago i had slight, flu symptoms, raised temp but not fever, headache and clogged throat. all has cleared up except the clogged feeling in my throat. no cough except for trying to clear it and no visible mucus?

There's a chance that it's more like a tic than a physical issue. After a noteworthy viral illness with postnasal drip, a sensation of something in the throat is normal, and can last. a few weeks. Of course there could be a mild post nasal drip actually going on, and depending on the time of year, allergy may be an issue. If the sensation worsens or doesn't go away, you may need an exam.
