So i'm having a testicular ultrasound tomorrow morning at 9:45am. I'm feeling very nervous and not sure what to expect. My doctor couldn't find my testicle lump upon examination and referred me off "just to make sure". 

Because of my hypochondria I've almost 100% convinced myself that i have cancer. I was just wondering if anyone out there has had previous scans like this? and can reassure me about my concerns?

Thanks
