Sensitivities can "stack" with repeated exposure. Even the most stoic should notify their physician regarding remarkable episodes.

Do you observe dust containment, by keeping dedicated shoes for the shop and immediately changing clothes? I've got an athsmatic kid, and try to be careful.

I run my cheapo air filter, if I start sneezing (not an asthmatic, my own self).

I was advised to rinse out my mouth and nose with tap water, when this happens.

This is the first mention you've made regarding this.
