Coughing Brown Mucus, Cramping in left leg, shortness of breath, pain and difficulty breath

Patient: I’m coughing up brown mucus, experiencing shortness of breath, pain when breathing and coughing, dizziness or lightheaded feeling upon coughing and standing, pain and cramping in my left calf, heart rate like I just finished a marathon, extreme hot and cold flashes (hot flashes I get really sweaty, even more difficult to breath, constant dizzy feeling… cold flashes all my joints stiffen, severe shivering, even hot showers and then wearing 4 sweatshirts and cover in 6 blankets doesn’t help me get warm)
