<s>[INST] i am an African man of 42 years of age with 104kg weight and 1.63m height. I have this nagging pain in my left arm extending to the left leg. The temperature of the left arm is higher than right arm. I can feel it its hot. This pain is not severe, it is extremely dull but it borders to numbness. It has been continuing for while. Strangely I only feel it at night especially after 22h00. What may be the cause? [/INST] Hi, as you mentioned the nagging pain which is at the borderline of numbness. I think it will be due to the nerve impingement. For which I will recommend you to perform some simple neck exercises for controlling the pain of the upper arm. Also by performing the core stability exercises and spine Strengthening exercises will help reduce the same for the leg. As the pinched nerve may always get missed by symptoms and variation one can confirm the same while understanding the MRI which can help understand the extent of the soft tissue .also as you are 104 KGS you need to perform Cardiorespiratory endurance training at a later stage to improve the overall body conditioning. With the grace of God I wish you a speedy recoveryregardsJay In Chat Doctor.  </s>
