What causes facial swelling?

Patient's question:

Anti-inflammatory medication, the swelling symptom on the face hasn't improved, frequent urination and urgency but unable to urinate is much better

Doctor's answer:

Analysis of the condition: This is likely due to psychological factors. If there were any issues, your liver function, kidney function, and ultrasound results would all be normal. It is estimated that if you continue to visit like this, the situation will remain the same.
Advice: I suggest you let go of your worries and avoid taking medication for now. If you are certain it is kidney stones, small stones (less than 1 cm) can often be flushed out through a large amount of urine. This is not kidney disease, so there is no need to worry. Please stop taking anti-inflammatory drugs as well, as this is not an infection. If it were an infection, your urinalysis results would not be normal. If you have further questions, please ask.
