Nerve irritation : Parasthesias( numbness,tingling, burning) that you are describing suggest a nerve irritation.A large nerve runs behind ( and on the outside) of your knee.(common peroneal).It has both motor and sensory branches.The nerve may have been' irritated' by a direct blow or more commonly by pressure ( or swelling) in the popliteal fossa( back of the knee).Bakers' cysts are most commonly involved.GL!
