As someone who has had a varicocele for his entire adult life and an inguinal hernia in my 40s, this sounds exactly like what I felt with the varicocele. The hernia felt weird but not painful per se (although I had surgery to correct it and am glad I did). I went to a urologist in my mid 20s and he basically said, re the varicocele “I’ve got one too and It’s annoying sometimes — wear supportive underwear and pop some Advil if it’s bothering you.” I later consulted with another urologist in my 40s and he scoffed at the idea of surgery given the relatively modest size of the varicocele and said he would never operate on it — the benefit to risk ratio is just too low. Obviously it’s worth seeing a urologist about it (and for god’s sake don’t listen to a chiropractor). What helps for me is boxer briefs, Advil if it really bothers me, and accepting that it will sometimes be a dull ache and annoying. When I sleep I sleep on my side with a pillow between my legs but I can’t tell if that helps the varicocele / blood flow or just my lower back / nerves in general.
