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.

Is My Newborn’s Head Shape Normal?
My son is currently 5 weeks old, and I’m feeling a bit anxious about his head shape. We have been incorporating brief sessions of tummy time into his routine each day.

Sore Bump in Armpit Area
Female, 41 years old. No ongoing medications. No previous medical conditions noted. I underwent a complete hysterectomy on May 7, which marks my significant medical history. For the past few days, I've experienced discomfort in my armpit, but there were no visible signs. However, a small bump appeared last night, and it seems to have enlarged slightly by this morning. I made sure to mark it in the photo I took. I opted not to apply deodorant today and chose to wear a loose-fitting shirt. The area feels tender without any pressure, and it becomes quite painful when I touch it. Currently, it doesn't feel warm to the touch. I am trying to remain calm, especially since it is on my left side. Can anyone offer suggestions about what this might be? I am considering a visit to urgent care after work.
Bright Red Blood During Bowel Movements
I’m a 27-year-old female, weighing 157 pounds and standing at 5’3". I have no significant medical history, nor do I use drugs, smoke, or drink alcohol. My only medication is Paxil at a daily dose of 40mg for anxiety. Today, I experienced a bowel movement, and upon wiping, I noticed bright red blood. It wasn’t mixed with the stool itself. Following the bowel movement, I felt some soreness inside my rectum. A few days earlier, I had a particularly difficult bowel movement that was hard to pass. As of now, I haven’t experienced any additional symptoms, but I am extremely worried that it might be a sign of colon cancer.
