Generalized soreness is not necessarily a precursor of cancer. The symptoms of generalized soreness are mostly seen in muscle strain, respiratory infectious diseases, rheumatic immune diseases, such as upper respiratory tract infection, pneumonia, etc. Patients may have generalized muscle soreness, fatigue, fever and other manifestations. In addition, cancer patients may also have the symptom of generalized soreness, but it is not the only symptom, and the common situations include: 1. Muscle strain: a lot of physical labor or whole body muscle exercise can make the muscle appear a lot of acidic metabolite accumulation, which stimulates the nerve endings and causes the symptom of generalized soreness. Generally through hot compresses, massage, rest, etc. can be relieved; 2, respiratory infectious diseases: such as upper respiratory tract infections, the onset of the patient will appear temperature rise, dizziness, headache, nasal congestion, sneezing, runny nose, etc., some patients will appear generalized aches and pains of the symptom, after systematic treatment, the symptom will be gradually relieved; 3, rheumatoid immune diseases: such as rheumatoid arthritis, rheumatism polymyalgia, etc., lesion Rheumatoid arthritis, rheumatoid polymyalgia, etc., the lesions invade the joints of the end limbs, which may lead to generalized muscle pain. It is recommended to treat the disease in time, so as to avoid the continuous progress of the lesion, limiting the muscle activity of the limb joints and leading to activity dysfunction; 4. Cancer: Cancer patients have no obvious symptoms in the early stage, and with the progress of the disease, the cancer cells will continue to release the toxins, which may cause the body to repeatedly and irregularly rise in body temperature, weight loss, nausea, vomiting, repeated diarrhea, constipation and other adverse reactions, so as to accelerate the metabolism of systemic tissues, thus producing a large number of acidic metabolites. As a result, a large number of acidic metabolites are produced, causing generalized soreness and pain. In addition, some patients with poor immune status or multiple metastases of cancer may also experience generalized soreness, but it is not a specific manifestation of cancer and cannot be used as a criterion for judging cancer. However, it is not a specific manifestation of cancer and cannot be used as a criterion for cancer diagnosis. Cancer diagnosis needs to be made through the comprehensive judgment of clinical symptoms, laboratory examination, pathological examination, imaging examination and other results. Therefore, if generalized pain occurs, the patient should first consider whether it is caused by exertion, and if it is suspected to be caused by diseases, go to the hospital to confirm the diagnosis and treatment.
