I have mergalia paresthetica. is it normal to have flair ups for days, and feel pain down front of leg and across top of knee?

Meralgia: This condition is usually caused by a pinching of a nerve coming into your upper leg and can occur in people who drive a lot, wear tight jeans, are diabetic and people who are overweight. Your symptoms may fluctuate or be steady. It is not a serious condition and if symptoms are severe, a neurologist could advise you best about diagnosis and treatment options like injections.
