killers will not work. A common cause is pulled muscles
(some where) starting from your back down to the toes
, sciatic nerve
passes through the area. try to find the muscle
which has been pulled - pass your hand over the length of your thigh and try to locate a "knot". HINT - all area of the thigh you will note is smooth except at the point where the muscle is pulled. Once you locate "that Knot" start massaging it with first 3 fingers (index, middle & bring) in a circle you will see the difference.
Sorry explaining in writing is difficult. If can contact me through Skype, i may succeed in explaining the procedure to you
