How does lactic acid causes pain in our muscles?

Due to temporary anaerobic respiration, while running or performing heavy exercise, the concentration of lactic acid  increases in the muscle cells as they lack oxygen.

In this respiration, glucose is converted into lactic acid with the release of a small amount of energy in the form of ATP.

The accumulation of lactic acid leads to painful movements or cramps in leg muscles.
