###Human: Why is there pain in all muscles and joints of the body? ###Assistant: Hi. I have gone through your reports (attachment removed to protect patient identity) and found nothing significant. First of all, you need to understand that if any small pain exists in our body for more than three months, then there is also an involvement of psychological factors which reduces our threshold of pain. You need to answer a few of my questions so that I can help you better. What do you do for your daily living? How much physical activity is there in your daily life? How many family members you have in your family? How is your threshold of irritability?
