Last week at work I had a bag of mortar dry mix dust extract dust into my face at close range. I was able to taste the dust as well as feel the gritty in my teeth instantly. A few minutes later my nose began to bleed and I spent the next couple hours puking and coughing up thick dry blood. A trip to immediate care clinic showed I was wheezing and very short of breath strep test and thrush test were done. Thrush came back positive and he noticed the rawness of my throat. Here it is a few days later and I have the worst upper respiratory infection ever with very sharp sudden pains in my left arm pit and chest. They were within minutes of each other and only when I deeply inhaled. There were 4 separate pains. My back (upper spine and chest feel like knives are digging into my body) should I be worried about pneumonia?
