### input:
My one year old has been having a swollen testicle that comes along with pain. He also has a dimple like indentation right on top of where his bladder sits but on the outside that seems to bother him as well. It s been growing deeper and bigger. He had an ultrasound and it showed swollen testicle but came back inconclusive on the dimple indentation. What can it be? Dr wants to run more test

### output:

Thanks for putting up your query at Chat Doctor. I am sorry to hear that your 1-year-old son has a swollen testicle. However, there are a few more things that I would have liked to know. Assuming that the swelling is actually affecting the testicle/testis and not any other structure in the scrotal sac, the first thing I would like to know is whether it was present since birth or whether it has developed recently. The second thing is whether it is associated with any redness and pain when touched. The third thing that I would like to ask is whether there is fever or any other symptoms present along with. Now let me come to the possibilities one by one. If it is present since birth (congenital), it could be some sort of tumor or even a simple HY Chat Doctor.  That however has fewer possibilities of being associated with pain. If however, redness or pain is present, a condition called torsion of testis may be present wherein the blood supply to a testis is disrupted. The pain and redness could also arise when there is inflammation of the duct of the testis known as the epididymis with or without affecting the testis, a condition called epididymo-orchitis. This could also be caused due to a urinary tract infection or a viral infection like mumps. This might be associated with fever. In some conditions an abscess or a collection of pus might also develop. I think that I have been able to give you an overall idea but if you get back with more details, I could perhaps be more precise. In light of the things I have told you, you might also like a briefing from your doctor on the possibilities he is considering.
