Hello hubby has been experiencing lower back pain for a while now. He's a mechanic and put it down to getting older. A few months ago he found a lump in his testicle as he had discomfort there... after coercion he went to the DR and got some antibiotics the lump went down and the pain in his testicle went too. Now it's back again and I'm starting to worry could it be something more sinister? He's urine is quite dark and he's often tired but I put that down to him working lots of overtime.. He's agreed to go to the Dr on his next day off but just wondering if anyone's partner has had anything similar?
