My mother has been having severe pain in nerves of left side of neck, shoulder and hand. The pain has started since 3 months. It was mild at first but now getting severe day by day. The pain has become so worse that it's very painful to even move that hand. ECG and blood sugar reports came out as normal. Several medications has been taken, as per the instructions given by a doctor, including Pregabalin 75, Hical Alpha 500mg, Mylamin. Doctor said it's cervical spondylosis but non medications helped much. She has also done neck and shoulder exercises but nothing helped much so far.
