Hello, your husbands Throat clearing could be explained by different origins but one thing is common, its due to clearing out of mucous, or perceived mucous, from ones throat or the area behind the tongue down to the vocal cords. However the most common causes could be explained by allergies, sinusitis or rhinitis if the presence of post nasal drip is noticed, Tonsillitis might also be one possibility.A good examination done by an ENT might be necessary to rule out the exact diagnosis and possibly the need of Antihistamines might be suggested by your physician. I wish him a prompt recovery.
