How could i know if my elbow is broken?

Xray: Unfortunately, you can't tell for sure without an xray. See your doctor.

Pain, loss of motion: I agree with my colleague who has already provided an answer, but there are some symptoms that while not specific, might point you in the direction of having a fracture. Significant loss of motion after a specific trauma or ongoing, unrelentling pain might signal a fracture. You can feel the ulna bone in the forearm significant tenderness or a palpable defect may be present. Good luck!

Pain: Pain, swelling, difficulty moving all would be potential signs of a fracture. I would not hesitate to be seen.

X-rays: The elbow is a very unforgiving joint. The least damage limits the range of motion significantly. If you have been injured and there is any limitation of motion or concern for undue swelling, pain or motion, then get seen and have x-rays. Even minor fractures in that region are important.

Pain & swelling: Limitation of movement and deformity are the most important sign, x- ray will the suspicion.

Self- diagnosis is: Not a good approach. Medical history, xray and physical exam normally yield an accurate diagnosis.

Broken elbow: You need an x-ray to confirm it. Usually, it is very painful and stays swollen for a prolonged period of time. It is also very hard to move it in seer fractures.
