Hey  I was just wondering could anybody help me out here, 

So I've had a feeling  of numbness in left testicle for almost 2 years now, I went to my doctor in November 2019 he said he felt a blockage in a tube under scrotum but he was not very clear on that with me, he referred me for an ultra sound and I was told it didn't matter if I paid or not there was a 3 month waiting list, so Feb came and no appointment then covid lockdown came in March 2020,and it is now May 2021 still no appointment,but the numbness is still there, its constantly there, its not painful in any sense but more of an uncomfortable feeling I've tried loose underwear/loose clothing/athletic supports and it's constantly there, should I be worried.? Some days are better then others, some days it goes from under testicle upto top of groin around the hip area, but most days it's just in the testicle area, any help would be greatly appreciated, thank you
