PATHOLOGY

Detailed explanation-1: -In the early stages of a fever, you often feel cold and start to shiver. This is your body’s response to a rising temperature. The blood vessels in your skin tighten up (constrict), forcing blood from the outer layer of your skin to inside your body where it is easier to keep the heat in.

Detailed explanation-2: -As soon as your brain shifts its internal thermostat to a higher set point to fight off an infection, the rest of your body goes to work trying to generate extra heat to meet that higher temperature goal. Suddenly, you’re technically below your new “ideal” core temperature, so you feel cold.

Detailed explanation-3: -If your hands and feet feel cold, but other parts of your body feel warm, a circulation problem that keeps blood from reaching your extremities may be the reason. This condition causes the blood vessels in your hands and feet to temporarily narrow when they sense cold, Dr. Rohr said.

Detailed explanation-4: -These rapid muscle contractions result in the chills – or shivers – we know well. Many people believe that chills only occur when a fever is present, but that’s not always the case. Most often, chills actually precede a fever and can even occur without one.
