I have 5 years feeling pain in my arms especially my right hand, with pain in my back, at the last i take XRay picture of my neck and found that the reason of my pain, it “cervical radiculopathy” in C6, C7, caused to reduce the time of my work, and also reduce my salary 🙁

For all developers my advice: be careful about your neck, make some exercises, do not spend hours on your computer, spend your time with your family or your plants 🙂 .
