I think I inhaled a bit of cement dust... Answered
Although I did my mixing outside (on a semi-rainy day) and held my breath while pouring the cement powder, I think I might have inhaled a tiny bit.
Not a lot, but enough for a bit of coughing afterwards. The coughing is over, but my throat now feels slightly sore, but not bad enough that I want to contact a doctor. Mostly just a bit irritated, that I hope will pass.
But can I eat or drink anything that might help this pass quicker? For lubricating the throat or something. Or will it go away eventually?
