<s>[INST] my left arm has been going numb. my pinky and my thumb I try using my left arm and I cant really grip anything. I try unlocking my house door with my keys and dont have the strength. it like my pinky and thumb wont work right. I am 43 years old. As Im typing my pinky and thumb are numb feel like needles on them. it happening more and more were my left arm and some of my fingers go numb. [/INST] Hello there I have read through your question and would like to tell you that pain and numbness in the finger s with pins and needles sensation is a sign of nerve compression. I would advise you to get an MRI cervical spine done. Meanwhile, try doing some stretching exercises. I hope that answers your question. If you have any further questions please feel free to write. Thank you for choosing Chat Doctor. </s>
