My Wife Is Suffering Lower Back Pain That Radiates Down

My wife is suffering lower back pain that radiates down her left leg and has trouble lifting her leg to get into the car. She has to lift her leg with her arm.
She had surgery on a severely pinched sciatic nerve caused by a herniated disc. She has constant pain down her right leg and her right foot became numb. The nerve was pinched for a long time due to a misdiagnosis from the hospital doctors.
This seems to be new.
