One year back, when my mother met a doctor for fever treatment, he injected the glucose to her left hand, then she experienced so much pain on injected area of nerve. After few days the nerve got pinched. Since then she's getting so much pain from her shoulder to total hand from time to time. It has increased recently and she's even experiencing numbness. She's is in so much pain. Below are the related photos of the pinched area of her left hand. Please help???
