Hi. Thanks for your query, albeit short and specific. The testis dislocation is die to excess mobility that the anatomy allows and not of much concern unless there is a pain or torsion or so. You can get a clinical actual examination by an Urologist to see the cause and the possible complication that can have. If present or anticipated, simple surgery will cure this problem. The another unrelated problem is itching and can be due to some form of dermatitis. Getting an opinion of an Urologist or if required that of Dermatologist will get a proper diagnosis and treatment. I hope this answers your both the parts of the query.
