Increased sweating can be due to several causes.
Anxiety tension itself is a cause of increased sweating.
Among other non medical causes alcohol, coffee, hot weather have role.
Common medical causes are increased thyroid activity, infection.
Growth or tumor, lung disease can also cause it.
The secretion at the back of throat can be from an infection.

You need to discuss with your doctor about the various possibilities causing the excess sweating & he may investigate to find out the exact causes of your symptom.
