Lately, ive been noticing that my left testicles feels smaller than my right when i feel it . Although physically it doesn't have significant size difference in comparison. Stillzl, the size is noticable in between them. Also when i touch it there is some kind of lump like feel in the left testicle and kind of gives a very slight pain when i try to press its.but, this problem is not persistent with the right one. I had nerve problems there because of an injury(not in the testes. But the legs). Its also persistent there. So, its really uncomfortable nowadays. I feel down because of all this pain.
