Tingling sensation in scrotum left side.

This episode started with heavy pain in left side lower abdomen going upto left testicle, so usg done and found minor left sided colitis in large intestine, was under medication and now ok and no further issue in lower abdomen but all of a sudden heavy pain started in left testicle, so I have done scrotum usg and found varicocele in left testicle grade 2. For the pain I have been given medicine Daflon 500 and ultracet(SOS).Have taken the medicine one ultracet and under medication of Daflon 500 for the last 7 days. Now the pain has gone but a strange tingling feeling comes and goes in the scrotum area, specifically left side and causing heavy discomfort. Prostate, kidney and liver related issue is not there as per USG report. Please help...
