Good evening I have been experiencing pain in my left lower limbs (hip, knee and foot), especially with prolonged period of walking and driving. I also experience a burning sensation on the left foot when seated for long. What could be the problem??

Nerve irritation? With prolonged sitting and walking exacerbating your symptoms a radiculopathy (nerve irritation) should be considered. Stretching at times may be of some benefit.

You should speak with your provider to confirm this my exam and other testing.

Best in health.
