My husband has had sciatic nerve pain since January, he also recently had an aortic valve replaced. his heart is doing fine and the hip and leg pain are better,but just the last few days he has had intermittent numbness and tingling on his left side(same as the sciatic pain) from his shoulder to his fingers and down the side and hip to his foot. The L5 is bulged ,but that doesn t explain the shoulder and side numbness???
