Thanks for writing in.
Feeling of clearing throat again and again is likely to be due to postnasal drip.
Other cause could be allergic if there is seasonal variation.
You can get your throat examined by ENT specialist
to rule out same.
At the same you can continue salt water gargling and steam inhalation which helps to resolve the problem.
I hope I have answered your query. Revert back in case you need further clarification.
