Why don’t we feel the tonnes of atmospheric pressure?

Atmospheric pressure, which is about 1 kg per sqcm of area, presses down on our body from all sides, but we don’t feel it as it is balanced by fluid pressure from inside our body. We can feel the difference during rainy season or when we go to places where atmospheric pressure is less, like hill stations, where due to higher fluid pressure, blood oozes out in blood vessels, making the skin over those pink. The reverse happens under water.
