The differences between fusion crystal pain and crystallization pain include different causes, different pain locations, different durations, different concepts, and different treatment methods. It is necessary to select appropriate conditioning measures based on personal conditions.

Differences:

1. Different causes: Fusion crystal pain refers to the pain symptoms that occur during the dissolution of crystals, while crystallization pain refers to the pain caused by damage to local tissues caused by crystallization.

2. Different pain locations: Fusion crystal pain generally manifests as pain in the ureter, while crystallization pain may cause pain in both the kidney and the ureter.

3. Different durations: Fusion crystal pain generally lasts for a shorter period of time, but crystallization pain may cause persistent pain.

4. Different concepts: Fusion crystal pain is the pain caused after treatment, while crystallization pain is the pain caused after complications.

5. Different treatment methods: Fusion crystal pain can be relieved by drinking more warm water to help expel the crystals. Crystallization pain can be improved through extracorporeal shock wave lithotripsy. It is necessary to undergo a color Doppler ultrasound examination to observe the size of the crystals and select appropriate treatment methods based on the size of the crystals.
