I experience thigh numbness then it starts to pain after 30 minutes of standing but when i sit down i feel relieved ?

Nerve: I believe that This positional symptom represents impingement of either a nerve root exiting the spine caused by a bulging intervertebral disc or a pinching of a superficial nerve at the level of the groin or hip depending upon which portion of the thigh is involved.. A neurologist can evaluate you and order appropriate tests in order to make a diagnosis and advise you of treatment options.
