What causes a tickle in my throat and coughing attacks?

Tickle in throat. It can be one of many things: laryngopharyngeal reflux (stomach acid coming up to the voice box), post nasal drainage, dryness, a weakness of the superior laryngeal nerve (the nerve that gives sensation to the voice box; usually viral), or even wax in the ear canal (there is a tiny nerve, arnold's nerve, that gets irritated and triggers a cough via a tickle in the throat). See an otolaryngoloist .
