Hello, I have just gotten over a cold that I ve had for well over two months. the duration coughing up yellow mucus. So much at times I would throw up. I know am still coughing up mucus, but still have muscle pain & weakness; & now in addition, I have chest pain. It started last night. Hurts when I take a deep breath, cough, or move certain ways, especially when bending forward. Pneumonia or pleurisy?
