Pain in my outer left leg that moves around. seems worse after sitting or standing. lying down w pillow under leg helps.

Nerve Impingement: Sounds like you may have a nerve impingement. The flexed position of sitting and the weight of your body when standing applies more pressure to the nerve thus worsening your symptoms, and when lying flat with a supportive pillow, the verve gets some relief. You need to see the Dr. for an exam and testing or a possible nerve impingement syndrome. Best wishes.

Go to see you Doctor: You clinical picture could be due to muscles spasm or arthritis whoever we need to rule out a possible DVT (Deep Venous Thrombosis ) so ho to see you Doctor as soon as possible for evaluation and treatment
