I experienced congestion, cough, and
laryngitis a day or two after exposure to large amounts of hay and
agricultural lime. Taking this into consideration, I'm a bit skeptical as to whether or not it was a cold or just an alergic reaction. The symptoms have drastically decreased. My nose is still half-way stuffy, and I'm still spitting up white phlegm, but it's more of an annoyance now than anything else. Some people I've talked to think that it's post-nasal drip.
