Hi there . Recently I was rushed into hospital with extreme pain in the testicles/scrotal area that radiates through to the lower back and pelvic area . Upon physical examination a specialist claimed it sounds like an infection and put me on a 2 week course of doxycycline. I'm nearing the end of my course of antibiotics and the pain has massively eased up but a dull pain still occurs and sometimes a burning sensation in the back / scrotum . Upon examining my testicles again I've noticed a vein like structure running up from the tail of the epididymis and what feels like a soft spot . It's hard to tell if it's a lump or not and I'm not sure if I should be concerned or not . I've been for sti testing to rule out epididymitis via sti infection and I came back clear . Could this be a tumour. Do tumours always result in a lump ? I'm going to speak to a doctor today to get checked once again and explain that the pain still hasn't fully cleared up . Just not sure if I should be worried or not .
