I have a really bad middle back pain that hurts when I move. And very sharp pains when I take deep breaths. I m able to walk but very slowly as the pain is sharp and hurts a lot. I ve also had a head ache since thurs and since then too I ve also not been able to hold food down. If I eat a meal it feels stuck on my chest and I cough and vomit it up. I was told last year that I had copd and just wondering of any of this is related. I ve been in bed since thurs. Attempted to work today but couldn t stand it. I m also freezing and shivering but my partner says my skin is burning Should I go to hospital
