I started playing football after many years gap. Now it's almost regular but while playing at a particular stretch my right thigh started paining and with in 2-3 hours it's get worse and I have to literally drag that leg. Then it's get normal with in a day or two . But during my morning jog it appears suddenly again and also during my first kick at football it start paying at same particular place of thigh . I have taken more rest and also started morning walk n running but this pain will start suddenly when ever I try to stretch my leg .
