Hi and welcome to HCM. Thank you for your query.
It sounds to me like it oculd be urinar infection so first rule this out by urine analysis and kidney
ultrasounds. Also it can be any STD
. Secondly, it can be casued by reduced blood flow in this area or nerve damage
. It should be evaluated by urologist
. SO dont ignore these symptoms,some antibioticas may be necesary if this is infection. ALso, try not to have sexual intercourse till this is healed. WIsh you good health.
