Left testicle swollen, tightness in area between anus and scrotum. whats happing? this is making me anxious its not normal.

Dr. to examine area: In general, testicle pain means a trip to the doctor right away because the testicle's blood supply can be twisted off (called torsion). What if only swelling or slight aches? That could be some other, non-urgent problem. One's primary care doctor can examine, because the details matter, such as where is the discomfort, how did it begin, how bad is it, what exactly is swollen, etc...
