Q: Scabies: Persistent Bumps on the Scrotum Explained

There are small lumps appearing on the testicles?

My family and I were treated for scabies on May 18.
A week later, during a follow-up visit, the doctor said we were cured.
However, after about one or two weeks, my husband developed a new bump on his testicle.
He applied some ointment on his own, and today he mentioned that it seems like there is another one (both are very itchy).
During this time, my son and I have been sleeping with him, and we haven't noticed any new rashes or itching symptoms (is it possible that symptoms from a second infection wouldn't appear immediately?).
Could this be a residual effect for my husband?

More Info

Scabies, caused by the Sarcoptes scabiei mite, is a highly contagious skin condition characterized by intense itching and a rash. The rash typically appears as small red bumps, blisters, or sores, often found in areas where the mites burrow into the skin, such as between the fingers, on the wrists, and in the genital area, including the scrotum.
In your case, it seems that your husband was treated for scabies, and although he was initially declared cured, he has developed new bumps on his scrotum that are itchy. There are several possibilities to consider regarding this situation:
1. Re-infestation: Scabies is highly contagious, and if one family member is infected, it can easily spread to others, even if they do not show immediate symptoms. It is possible that your husband was re-infested either from contact with someone else who has scabies or from contaminated bedding, clothing, or towels. The incubation period for scabies can vary, and symptoms may not appear until several weeks after exposure, which could explain why you and your son have not shown symptoms yet.

2. Post-scabies itch: After successful treatment of scabies, some individuals may experience persistent itching and irritation for weeks or even months. This condition, known as post-scabetic itch, occurs because the skin is still healing from the irritation caused by the mites. The presence of bumps could be a result of this irritation rather than a new infestation.

3. Allergic reaction: It is also possible that your husband is experiencing an allergic reaction to the treatment used for scabies, such as topical creams or medications. This can lead to localized irritation and the development of bumps that may resemble scabies.

4. Secondary infection: Scratching the affected area can lead to secondary bacterial infections, which may present as red, swollen bumps that are itchy and painful. If your husband has been scratching the area, it could lead to such an infection.

Given these possibilities, it is essential for your husband to follow up with a healthcare provider. They may recommend a thorough examination to determine whether the new bumps are due to re-infestation, post-scabetic itch, an allergic reaction, or a secondary infection. If it is determined to be a new scabies infestation, the healthcare provider may prescribe a different treatment regimen or recommend additional measures to prevent re-infestation, such as washing all bedding and clothing in hot water and vacuuming living areas.

In the meantime, it is crucial to maintain good hygiene and avoid close contact until the situation is resolved. If you or your son develop any symptoms, such as itching or new rashes, it would be wise to seek medical evaluation promptly.
In summary, while your husband's symptoms could be related to a variety of factors, including re-infestation or post-scabetic itch, a medical evaluation is necessary to determine the exact cause and appropriate treatment.
