I have at least a slight fever . My muscles feel really sore. I felt like my air way in my throat was closing up. I just puked up a small amount of blood . I looked at the back of my throat and there is blood draining down my throat. I started puking up blood very rarely back when I was a teenager. It s gotten worse over the years. It s been about 10 years since I puked up blood for the first time ever. I did over take on over the counter medications for a while. Is it possible that the puking of blood could be due to over taking on medications? What I thought this was isn't even close to what I found out I ended up having.
