Lifestyle­ adjustments such as a nutritious diet and regular e­xercise can significantly improve the­ situation. Medication or therapies may also be­ viable solutions.

To ease the pain, take a break from masturbation for a while. Concentrate on relaxation methods and light exercises. If the pain doesn’t go away, please consult with a healthcare professional.
