Been having suffering testicular issues for a couple of months now. The issues cropped up after a couple of emotional shocks which sent me into a low intensity depression. The issues are: one testicle has diminished in sized by about 1/3 while the other has nearly doubled in size though this doubling is not by any means consistent over time, whenever I am overly stressed for long periods of time it gets to that size otherwise it maintains a relatively normal size (slightly enlarged from before these issues cropped up). While enlarged the testicle feels solid and uniform (no lumps of any sort), it feels heavy and gives a dull aching pain even when sitting perfectly still. It's not an infection as there's no blood, discolourations, pus,etc in the urine or seminal fluid.
Does anyone know any conditions which could explain this? My own searches on the subject ruled out cancer a long time ago as cancer does not go away once triggered and I have had no lumps prior to the issues or since and the only culprit/disease I can find that matches my symptoms somewhat is the Varicocele but if anyone can confirm this I'd be much obliged.
