Best Answer

When you bump your knee (or other body parts) there is some damage to the various tissues involved. The body has two main types of fluids that constantly circulate, which are blood and lymph. When there is damage to the body, these fluids tend to leak out of their normal pathways and vessels, and to pool in the damaged area. Bumps are formed as a result of added fluid. Eventually the excess fluid will be reabsorbed into its normal circulation, and the bump will heal.
