Feeling pain everywhere in the body may be caused by overwork, mental factors, inflammatory pain, traumatic pain, neuropathic pain, malignant tumor pain and other reasons. 1. Overexertion: after doing strenuous exercise, the muscles accumulate too much lactic acid that cannot be metabolized in time, resulting in pain everywhere in the body. 2. Mental factors: excessive mental tension, anxiety, depression and other psychological disorders, so it feels like the body hurts everywhere. 3. Inflammatory pain: rheumatoid arthritis, rheumatoid arthritis, ankylosing spondylitis, etc., can cause pain everywhere in the body. 4. Traumatic pain: skin, ligament, fascia, bone and other injuries caused by pain, such as fractures, burns, acute lumbar sprain. 5. Neuropathic pain: such as post-herpetic neuralgia, diabetic neuropathy, etc., resulting in pain everywhere in the body. 6. Malignant tumor pain: for example, stomach cancer, liver cancer, pancreatic cancer, etc., because the tumor infiltrates the surrounding organs and the tumor is compressed, which causes pain all over the body. If you feel pain everywhere in your body, it is recommended to consult a doctor in time to find out the cause of the disease and treat it as early as possible so as not to miss the disease.
