What are the differences between rheumatism and bone cancer

Some friends have suggested that they feel joint pain that affects their normal walking, and the pain is particularly severe when they are tired. Sometimes they can't sleep well at night. Could joint pain be bone cancer or rheumatism? Bone and joint pain with this clinical symptom is caused by bone cancer, or it may be caused by rheumatism. So what is the difference between rheumatism and bone cancer?

Both bone cancer and rheumatism will cause pain clinically. Therefore, before any relevant examinations are done, it is impossible to diagnose any disease based on the symptom of bone and joint pain alone. If the patient already has the symptom of bone and joint pain and it has affected his normal life, he must go to the hospital for treatment.

The main clinical symptoms of bone cancer include a hard lump on the surface of the bone, which may or may not be painful. First, consider whether it is bone cancer; pain or swelling in the bones and joints, which is often worse at night and not necessarily related to activity; pain as a symptom of bone cancer can be continuous dull pain, or pain that is felt only when pressure is applied; spontaneous fractures

Rheumatism has the following characteristics: (1) The pain lasts for a short time, generally 12-72 hours, and the longest is no more than 3 weeks, and it is mostly in large joints, such as the knees, elbows, shoulders, etc. (2) Migratory pain, that is, after the pain in one joint has improved or has not improved significantly, another joint is affected and pain occurs. (3) Joint pain is accompanied by redness, swelling, tenderness around the joint, and refusal to press.
