I think that you can get to the hospital right now. It is possible that the patient is developing a condition called sepsis. I would have admitted any patient who would come to me with similar effect. I would have liked to get the diagnosis as soon as possible. I think I would like to see the blood culture, urine culture and test him for other infections. I think I would suggest intravenous antibiotics, and other supportive treatment. I hope that the information helps you to know about the symptoms. I have tried to make it as simple as possible for you to understand. Best of luck. Dr Mittal.
