i have a slight swelling in left scrotum but didn't notice any kind of lumps so far. This coincidently happned the day after my treadmil work out at the inclination of 12 and walking speed of 7.2 KM (Usually my inclination would be at 6). Hence i am not sure if its because of trauma or something else. If i use ice pack the swelling is going away but coming back in few minutes. also swelling is reduced when i lie down. Its not actually paining but i am having some kind of burning sensation in scortam , groin and thigh together. Booked GP appointment in a week but am really worried and not able to concentrate on my work thinking about cancer
