The weather is cold, my limbs are weak, and I feel sore all over. Do you know what is going on?

Drink Huoxiang Zhengqi or eat something to cool off the heat.

But are her hands and feet cold on sunny days or cloudy days?

If your hands and feet are cold on a sunny day, you'd better see a doctor.

I belong to the kind where the temperature changes with the weather.

Raining on cloudy days is also cold hands and feet.

Cooler than the others.

It may be deficiency cold.
