[Closed] Trapped nerve help

For the last week or so I have been suffering with a trapped nerve ?!!?? I could be wrong.

Symptoms
When I wake up in the morning or at night for a wee my whole back of right leg feels incredibly tight from ankle to buttocks to the point that I have literally move on my left hand side its quite painful but defo muscle pain
By the time I have been up in the morning say 10 mins its loosened off and feels okay for the rest of the day can walk/activities all normally.

Wife massaged leg yesterday was ultra painful this morn when woke ! but 10 mins on feet all okay again !

Is this the symptom of a trapped nerve ?

Any stretching exercises you can recommend ?

many thanks
