I saw your post regarding Silica exposure and I had a similar experience recently with similar symptoms. I wanted to check in and see if your symptoms persisted or if its something that dissipated with time?
Hope you are well and thank you for your time in advance.
Welcome to the MedHelp forum!
Silicosis is of two types: chronic that occurs from more than 20 years of exposure, and accelerated from 5-10 years of exposure. There is also a very acute variety that ours after very short term-even less than a year's exposure of huge quantities of silica. Susceptible individuals can also develop silicosis after a few months of exposure.
So yes, a single exposure can cause silicosis years later, but chances are pretty rare. If you have phlegm years later, cause could be a chronic obstructive pulmonary disease other than silicosis.
Hope this helps. Take care!
