Entity 1: Lumbar muscle strain

Entity 2: Fatigue

Health consultation description: For example, when I bend over and then straighten up, I clearly feel a *, not pain, and I notice that changing the posture of my waist also produces this sensation. What’s going on? Doctor’s response: In cases like yours, it could be #, or it could be a herniated disc, causing symptoms by compressing the nerve. It is recommended that you go to the hospital for an X-ray or CT scan to confirm whether you have symptoms of a herniated disc.

The predicted entity relation is: DS

Entity 1: Fracture of the right radial head

Entity 2: Calcium supplementation

Health consultation description: #. Some doctors say surgery is not needed, while others say it is. Would like to hear opinions. Thank you. Doctor’s response: Condition analysis: Hello, for this type of fracture, it should first be reduced, then stabilized, and then undergo rehabilitation treatment.

Doctor’s response: Normally, a fracture should have healed well after a year, and the internal fixation can usually be removed. I suggest you go to the hospital for another check-up and see if the fracture has completely healed.

The predicted entity relation is: UKN
