Could This Be Hand, Foot, and Mouth Disease?
Age: 9 months Gender: Male Location: North Carolina Seeking advice on whether this could be hand, foot, and mouth disease. Recently, my baby developed a rash on his bottom accompanied by what resembled thrush, starting last Sunday. I took him to the doctor on Monday morning, where they prescribed a cream for the rash and a topical treatment for the thrush, instructing us to apply it four times daily. Although he began the medication Monday and Tuesday, there was an issue with the prescription for the ointment. The thrush appears to be improving; however, the diaper rash continues to be a concern. This Tuesday, he started preschool, and today he has developed these new symptoms. I’m concerned that what appeared initially as diaper rash might actually be an early sign of hand, foot, and mouth disease. I haven't noticed any additional bumps on his body at this point. I have scheduled an appointment with the doctor for tomorrow and so far, he has shown no signs of fever.

It’s understandable to be concerned, especially with a young child. Hand, foot, and mouth disease (HFMD) is a viral infection commonly seen in young children and characterized by fever, mouth sores, and a rash on the hands and feet. However, many other conditions can cause rashes and general discomfort, particularly in infants.
Explanation:
The rash on your baby's bottom, coupled with what looked like thrush, could have several explanations. Diaper rashes are quite common, and thrush (oral yeast infection) can occur simultaneously, especially if there are factors like antibiotics or a moist environment. HFMD typically presents with lesions in the mouth, a rash on the hands and feet, and sometimes fever, which your child hasn’t exhibited yet.
Next Steps:
-
Monitor Symptoms: Keep an eye on your baby's symptoms and note any new developments, particularly:
- The appearance of any bumps or sores on the hands, feet, or inside the mouth.
- Signs of fever or any unusual fussiness that may indicate discomfort.
-
Continue Current Treatments: Follow the doctor's instructions for the topical treatments for both the rash and thrush diligently, even if the rash appears persistent. Consistency is key in treating diaper rash.
-
Comfort Measures: Ensure your baby stays comfortable by:
- Changing diapers frequently to keep the area dry and clean.
- Applying a barrier cream (like zinc oxide) to protect the skin if not already advised by your doctor.
-
Follow Up with the Pediatrician: Since you have an appointment scheduled for tomorrow, bring up all your concerns, including the possibility of HFMD. Your doctor can perform a thorough examination and make the best clinical judgment.
-
Hygiene Practices: Since your baby has started preschool, strengthen hygiene practices by washing hands frequently and keeping toys and surfaces clean to prevent the spread of any potential infections.
Let me know if you need further clarification or advice. Your child's health and comfort are paramount, and your proactive approach is essential.

Concerns About Toenail Health
A 25-year-old woman with asthma, who weighs 117 pounds and stands at 5’1, has been facing a troubling toenail issue. In 2020, she noticed that her big toe's nail and the adjacent one on the same foot developed a horizontal fissure that originated from the lunula and extended upward with the nail’s growth. The texture of the toenail became unusually hard, resembling the growth of a superimposed layer, yet there was minimal discoloration—just a hint of yellowing that wasn’t particularly alarming. Despite the nail growing out since then, one vertical edge of the large toenail has turned exceptionally rigid, presenting a challenge when trying to trim it. Interestingly, while there is no visible discoloration, a peculiar odor reminiscent of spoiled cheese emerges, particularly when she removes the debris accumulated underneath the nail. The firmness of the nail is such that it adheres to her fingers, prompting a need for thorough handwashing afterward. The odor becomes prominent when she examines it closely—using her eyes to get near enough for clipping. Although the affected toenail produces this unusual smell, her overall foot hygiene remains intact. She rarely experiences foot odor, except for when she wears damp sandals that have come into contact with dirt, which emits a different scent altogether. Throughout this situation, there has been no pain or discomfort associated with her toenail condition. She plans to share an image in the comments depicting the fissuring that occurred in 2020; she requests that readers overlook the bruising visible in the photo, which resulted from an incident involving a 45-pound weight that fell on her foot during Christmas, clarifying that the cracking predates that incident.

Managing a Pec Tear: Seeking Guidance
I am an 18-year-old male residing in Ireland, and I sustained a pec tear approximately five months ago. I initially didn’t recognize the injury until about two weeks later, when I noticed bruising on my arm. Afterward, I sought medical help at the hospital; however, the long wait combined with severe pain led me to leave before receiving treatment, opting instead for some pain relief medication. Now, I’m contemplating whether it is feasible for me to live with this injury. I recently passed my army enlistment test and would like to know if surgery might be necessary before proceeding further. Whenever I flex my affected muscle, I observe a peculiar dent in the area, and it seems as though the tendon is detached. What steps should I consider taking next?
