There is a painful lump at back/top of my right testicle and the same testicle rises up when i inhale deeply?

You should consult a urologist for evaluation. This could be a benign cyst or spermatocele which often resolves on its own. An ultrasound will most likely be ordered and treatment options will be discussed.

A painful lump such as you describe is commonly due to epididymitis. If so, it can be determined by physical examiination. See a urologist for accurate diagnosis and treatment.
