Right sciatica presents as pain in the right buttock, right posterior thigh, and right posterior lateral calf. Patients may feel a mild tingling or vague pain with numbness or a burning sensation, which in some cases may cause difficulty walking when the pain is worse. Typical symptoms of right sciatica: First, the pain is often paroxysmal or may be persistent and can usually be triggered by coughing, sneezing, bending, stretching, squatting, defecating, and other actions. Second, the pain is clearly regional, mainly located in the right buttock, behind the right thigh, the posterior and lateral aspects of the right calf, and the lateral aspect of the right foot. Third, the nature of the pain is mostly dull, but it can also be burning or pinprick-like pain, and can also be accompanied by numbness. The pain is mostly radioactive, radiating downward along the right buttock to the calf, and can also appear as abnormal skin sensation in the area of sciatic nerve innervation, as well as muscle weakness and claudication.
