If you have not strained yourself in anyway it may not be related to testicular torsion but since you are seeing a lump in your scrotum it does need to be examined by your physician as this could be related to a tumor,infection, or something as simple as water retention. This does sound related to the problem you are having obtaining an erection and if it is infection related then once the infection is cleared up your ability to have an erection should return. But this is not something that I would put off I would have it checked out by your physician as soon as possible as if it could be testicular torsion the sooner treatment is given the better the outcome.
