What is a pinch nerve/how does it feel and how can you stretch out pain from you!

i went walking for a while yesterday!. (!.!.ok i admit it i was shopping in the mall for a few hours!.!.!.) and i'm not exactly sure what a pinch nerve is!.!.but i think i have one in my right leg!.!. it goes from behind my thigh (almost upto under my rear) down to the back part of my calf!. it hurts!.!.and i feel like i can't stretch it out!.!.when i try to stretch my leg it only stretches the inside leg muscle!. i took some advil to try to relieve the pain but i just want to know what kind of stretch i can do to maybe help stretch it out!?

and maybe i'm making a mistake calling it a pinch nerve, maybe someone could explain to me exactly what that is!? we thought my dad had one a few years back because he had pain in his leg and started limping for about a week or so but it turned out to be brain cancer!. i don't think i have brain cancer lol i'm not a hypochondriac (sp!?)!. so i just want to clarify what it feels like and what it is as well!.

any information is appreciated!.

i hate when people do this but i always award best answer and rate well for any kind of helpful posts/information!.Www@Answer-Health@Com
