I have a sore throat that won't go away for 2 weeks along with some chest pains and shortness of breath, and more recently when I inhale deeply I can hear a crackle noise right below my neck and I suspect that I have silicosis or pulmonary fibrosis because I smoked some weed which I think is laced, because it happened after I smoked the weed, I heard of people put glass or silica in the weed to add weight, and I went to the doctor today and explain to him my symptoms, but I didn't say about smoking laced weed, and he looked at my throat and says he can see some congestion or something, and listened to the front and back of my 2 lungs and says everything is normal and looks like I got a bacterial infection and I asked him if I need a xray and he says no and I asked if I got silicosis or fibrosis and he says no, and I made up a story about cleaning my garage where there is a lot of broken light bulbs and that I have a nasal congestion so I have to inhale through my mouth and I could possibly get glass particles inside my lung, but he says it's not likely then he prescribe me arizthromycin 500mg 3 tablets for 3 days, so if I took it my symptoms go away then my doctor is right about a bacterial infection and I haven't got silicosis or fibrosis, right?
