Understanding the Cause of These Blisters
I am reaching out on behalf of my four-year-old daughter. About two weeks ago, she first experienced an itchy spot on the bottom of her foot. A week later, some small bumps appeared, and a pharmacist suggested it could be hand, foot, and mouth disease. Today, the situation has escalated significantly. The small bumps have developed into painful blisters, and she's expressing discomfort when they are touched and they also continue to itch. Thankfully, the rash has not spread to any other areas of her body. We recently visited a general practitioner regarding some Molluscum contagiosum lesions and were advised to leave those untreated. We plan to consult a GP as soon as possible, but I would appreciate any insights into whether this condition could be contagious and if there are any immediate home remedies we might try in the meantime.

It sounds like your daughter is experiencing painful blisters on her foot that may be related to a viral infection like hand, foot, and mouth disease (HFMD) or possibly another issue. Here’s a breakdown of what you’re facing and some actionable steps you can take.
Main Points
- Possible Causes: Itchy spots developing into blisters can indicate HFMD or other viral infections. Molluscum contagiosum typically does not cause blisters, but it’s good to monitor for any changes.
- Contagious Nature: Hand, foot, and mouth disease is contagious and spreads through contact with an infected person’s secretions.
- Immediate Care: There are home remedies to soothe the discomfort and itching while you wait for the GP appointment.
Explanation
The development of itchy spots that evolve into painful blisters is common in children and often involves viral infections. HFMD usually causes sores in the mouth plus blisters on the hands and feet. Although your daughter’s rash hasn’t spread elsewhere, it’s wise to monitor her closely due to the infectious nature of HFMD. Molluscum contagiosum, on the other hand, is less symptomatic and usually resolves on its own over time but requires observation.
Next Steps
-
Comfort Measures:
- Cool Compress: Apply a cool, damp cloth to the affected area to help reduce itching and discomfort.
- Oatmeal Baths: Consider giving her an oatmeal bath to soothe her skin. You can use colloidal oatmeal available at drugstores.
- Topical Care: Use over-the-counter hydrocortisone cream (if contraindicated, please confirm with the pharmacist) to help with itching.
-
Monitor Symptoms: Keep a close eye on her condition. Look for signs such as increased pain, fever, or if blisters spread to other parts of her body.
-
Prevent Contagion: Encourage good hygiene practices, such as frequent handwashing, to minimize spreading the condition if it is indeed HFMD.
-
Consulting the GP: Make sure to discuss the duration and nature of the blisters with the GP for appropriate diagnosis and management.
Taking these steps should help manage your daughter’s symptoms until you’ve seen the doctor. Focus on keeping her comfortable and safe during this time, and don't hesitate to reach out again if you have more questions or concerns.

Understanding the Reality of End-Stage Pancreatic Cancer
Navigating the complexities of end-stage pancreatic cancer can be overwhelming, and I'm seeking clarity on what lies ahead. My mother, who is 59 years old and weighs about 115 pounds, received her diagnosis of terminal pancreatic cancer in October 2025. Unfortunately, she has largely rejected the option of chemotherapy and is consuming her pain relief medications—specifically oxycodone and morphine—at an alarming rate. While I’m not worried about the dosage, the severity of her pain has reached a level that is becoming unbearable. Despite this, she is adamant about avoiding any hospital treatment, even though that's where she would receive the most effective pain management. I’ve attempted multiple times to get her medical attention, calling both hospitals and emergency services. However, due to her refusal for assistance, they have also turned us down. It was explained to me that taking her against her will could be considered kidnapping. After consulting with various healthcare professionals, I have been informed that her time may be measured in days or weeks. There’s also a chance that she could slip into unconsciousness, leaving me deeply unsettled. I am already in a state of mourning, yet I am desperate to understand what to expect in the coming days. It is crucial for me to prepare myself—emotionally and mentally—so that I can help ensure her comfort in these final moments. Plans are underway to engage hospice care, but the uncertainty fills me with apprehension. This is my mother, and I want to alleviate my fear so I can provide her with the support she needs as she nears the end of her journey. I yearn to be present for her without being entirely consumed by grief before she passes away. Any guidance or insight you could provide would be invaluable. I'm at a loss for what steps to take next and truly desire to navigate this situation with as much grace and readiness as possible.
Concerns After Gallbladder Surgery (Three Weeks Post-Op) - Is It an Infection?
Profile: - Age: 35 - Gender: Female - Height: 5 feet 4 inches - Weight: 160 pounds - Ethnicity: Asian Duration of Symptoms: Last Three Weeks Location: United States Recent Medical History: Nearly three weeks have passed since my gallbladder removal surgery. Over the last few days, I've noticed a small amount of unclear fluid coming from the incision. I just observed what seems to be pus oozing from the surgical site. Although there is slight tenderness when I move or touch the area, it isn't painful. Thankfully, I haven’t experienced any fever or chills, and there’s no unpleasant odor emanating from the wound. Should I continue to clean it with soap and water, or is it necessary for me to visit the emergency room for further evaluation?
Exploring Inositol and CoQ10 for Managing PCOS Symptoms
As a 28-year-old female, I have faced the challenges of polycystic ovary syndrome (PCOS) since my teenage years. Starting from the age of 16, I have dealt with highly irregular menstrual cycles, occurring anywhere from three to eight months apart. My diagnosis has been substantiated through two ultrasounds and blood tests revealing elevated androgen levels. Despite maintaining a healthy diet and leading an active lifestyle—balancing my work as an environmental biologist with gym sessions alongside my husband—I continue to wrestle with weight management. Other symptoms impacting my daily life include significant hair loss, unwanted facial hair, and persistent fatigue. In my journey to manage PCOS, I previously sought counsel from a gynaecologist, who primarily suggested hormonal birth control as the main approach to alleviate my symptoms. Although I adhered to this recommendation for several years, the hormonal changes negatively impacted my mood, leading me to discontinue its use. Another alternative proposed by my gynaecologist involved androgen blockers, but these are not suitable for me since my husband and I plan to start a family in the next two to three years. Recently, my research led me to discover that supplements like Inositol and CoQ10 might effectively combat insulin resistance and lower androgen levels. They are purported to improve various symptoms associated with PCOS, including the regulation of ovulation, all while boasting minimal adverse effects. I am curious about the viability of these supplements as alternatives to hormonal birth control or androgen blockers in managing my PCOS symptoms.

Navigating Ear Infections While Traveling in Thailand
**Age:** 23 **Height:** 6'3" **Weight:** 88 kg **Medication Taken:** 1000mg Bactoclav - Amoxicillin with Potassium Clavulanate, along with pain relief and antihistamines. **Summary:** I’m hesitant to consult a doctor overseas only to receive a prescription for the same antibiotics available at a local pharmacy for a fraction of the price. What strategies can I employ to effectively manage this persistent ear infection? Am I being too hasty in my expectations? I have a long history of ear infections, often triggered by exposure to water or any activity impacting my ears. I regularly use a specialized oil before showering to prevent water from entering my ears. While backpacking in Thailand, I've developed a particularly severe ear infection over the last several days. Initially, a course of 500mg amoxicillin seemed effective, but significantly, just yesterday my condition took a downturn, shifting from nearly healed to painfully inflamed. Now, my ear is not only swollen but also incredibly sore. In an attempt to combat this, I’ve been taking 1000mg Bactoclav - Amoxicillin and Potassium Clavulanate, having consumed seven tablets in the last two days; unfortunately, there's been no noticeable improvement. I’m reluctant to seek medical attention, fearing I would be prescribed the same medication I could acquire from a pharmacy, albeit at a much higher cost. Yet, I’m also starting to question the efficacy of the pharmacy’s medication. I’ve only recently begun the stronger treatment since my symptoms returned. Any advice would be greatly valued! In addition, I’d like to share that just a week into my four-month journey, I feel as though my ongoing ear issues are gradually dominating my life. I am incredibly grateful for this travel opportunity, and while my health isn’t at risk in a serious way, these ear complications are becoming quite overwhelming. Could there be surgical options available? Might there be an underlying health concern that I’m unaware of? It doesn’t seem normal to be plagued by constant ringing, popping sounds, and wax buildup in my ears. Moreover, it feels excessive to have to apply products in my ears every time I shower.
