Varicocele generally does not cause a burning sensation in the urethra. The main symptoms of varicocele are a dragging pain in the testicles, especially after long periods of standing, sitting, or intense physical activity. The pain becomes more pronounced, and the affected testicle may noticeably sag when standing. A color Doppler ultrasound can confirm the diagnosis. The most common cause of urethral burning sensation is urethritis or the presence of stones in the urethra, which needs to be confirmed through routine urine tests. If an increase in white blood cells is observed during the urine test, it can be diagnosed as a urinary tract infection. This condition requires timely treatment with antibiotics, and typically, a course of seven to ten days can lead to recovery.
