Good day girls! I can't understand transparent mucus from my nose, temperature 37.5 for the second day. Terrible sleep, often wakes up and cries, daytime dreams only on hands. I suspect teeth. According to time, the lateral incisors should be, but I don't see them in my mouth. Could it be an upper respiratory infection? Has anyone experienced this?
