Three-Month-Old Baby with Persistent Blisters on His Back

6/29/2025, 2:00:44 AMMale25-34

A three-month-old male infant has been observed to have blisters located between his shoulder blades since birth. Upon delivery, two pediatricians examined him and remarked on the unusual nature of the blisters. They mentioned that such formations typically occur on the hands or arms as a result of infants sucking on them while in utero; however, it was evident that this was not applicable in this case due to the blisters' unusual location. The preliminary assessment indicated the condition might be "erythema toxicum," a diagnosis supported by his primary pediatrician during a check-up at one month old. However, research indicates that this condition typically resolves within a week, leading to concerns given the blisters' persistence. Now at three months, the blisters have diminished somewhat, yet a significant red area remains, which continues to develop into a large blister. This does not appear to be spreading, and the baby does not seem to experience any discomfort. Although the blisters are left intact and are not deliberately burst, they tend to rupture on their own within a couple of days after forming. All maternal laboratory tests have returned negative results on two separate occasions. Additionally, samples were taken from the affected area (excluding the blister fluid) and those tests also yielded negative results. At this point, we are uncertain about the nature of this condition and are contemplating a referral to a dermatologist for further evaluation. The pediatrician maintains that these blisters will likely heal over time, yet their current state appears stagnant.

It sounds like you're understandably concerned about your baby's persistent blisters. Here are some important points regarding his condition, along with straightforward next steps you can take.

Main Points: The blisters on your baby's back have been present since birth, and while they are somewhat stable, they have not resolved as expected. The situation warrants careful observation but may not necessarily indicate a serious underlying issue.

Explanation: Based on your description, the blisters seem to be persistent and unusual for a three-month-old. Conditions like erythema toxicum typically resolve within a week, while your baby's situation does not align perfectly with this. Since the blisters seem to lessen and rupture without causing pain, it's encouraging that he appears comfortable and symptom-free. However, it’s vital to investigate any persisting skin issues to ensure proper care.

Next Steps:

  1. Monitor the Blisters: Keep a close eye on the blisters' size, color, and number. Document any changes, including when they rupture or if new blisters develop. This information will be helpful for future consultations.

  2. Maintain Proper Care: Ensure the area remains clean and dry to prevent any secondary infections. Avoid applying creams or ointments unless advised by a healthcare professional.

  3. Prepare for Further Evaluation: Since you mentioned a potential referral to a dermatologist, it may be wise to gather any pertinent information such as previous examination notes, lab results, and photos of the blisters over time to share with the specialist.

  4. Follow Up with Pediatrician: If any changes occur, such as signs of discomfort, fever, or increased blistering, contact your pediatrician immediately for reassessment.

Your concerns are valid, and it's good to be proactive. The dermatologist will be equipped to provide a detailed evaluation and possibly a clearer diagnosis, ensuring your little one gets the care he needs. Please don't hesitate to reach out if you have more questions or need further reassurance.

Using Crutches for a Mild Calf Strain: Is It Justified?

Today, while I was at the gym, I encountered a bit of an issue. After completing a set of push-ups, I made an unusual movement while rising, which caused my foot to extend too far up, leading to a sharp sensation in my calf. Although I can still walk, the area is quite tight and sore. If I accidentally flex my foot too much, it exacerbates the discomfort. The muscle feels both tense and sensitive. I strongly suspect it’s a minor calf strain, likely a grade 1 injury. Interestingly, I experienced a similar situation just three months ago with my other leg. I didn’t take that instance seriously, which led to the development of Achilles tendinitis, prolonging my recovery significantly. I’m eager to avoid a repeat of that scenario. I’m seriously considering using crutches and minimizing weight on my leg for a few days, even though I feel a bit ridiculous since I can walk without limping. Am I being overly cautious? I just want to prevent any further complications. I've been icing and elevating the affected area all afternoon, but if the discomfort persists, I don’t want to take any chances.

Experiencing Ongoing Lightheadedness for Several Days

I'm a 37-year-old female, standing at 5'4" and weighing 98 pounds, living with multiple sclerosis. My alcohol intake is minimal, and I occasionally use a vape. My current medication regimen includes Copaxone administered three times a week, 40 mg of Lexapro once daily, Armodafinil 50 mg only as required, Claritin as necessary, and a daily dose of 50 mg of vitamin D3. Over the past five days, I’ve been experiencing an unusual sensation that I can only describe as lightheadedness. It feels as though I might faint, though I haven't actually lost consciousness and there's no sense of spinning involved—just a vague feeling of disorientation. Oddly, it seems to be localized to the right side of my head. I'm at a loss for how to characterize this sensation beyond that. These episodes, which persist for just a few seconds, occur intermittently throughout the day, regardless of whether I'm lying down, standing, completely still, or on the move. Alongside this, I've been battling notable fatigue. I ensure that I hydrate adequately and am not dealing with any nasal congestion. I initially suspected that the Armodafinil might be contributing to this lightheadedness, so I decided to stop taking it, especially since it hasn't been effective for my fatigue either. Despite this change, my condition remains unchanged. Recently, I dealt with a throat viral infection that resulted in a sore throat and a mild fever, though I tested negative for strep throat. Could this be indicative of a flare associated with my MS? Might it stem from residual effects of the viral illness? Or is there a chance it's something more serious? I appreciate any insights.

My Experience with a Torn Plantar Fascia: Seeking Guidance

As a 25-year-old, I experienced an alarming incident about two months back. While I was dancing, a loud popping noise echoed, followed by an intense pain in the arch of my foot. This pain was so severe that I couldn’t apply any pressure without feeling agonizing discomfort. I sought help from my general practitioner, who promptly arranged for an ultrasound. The results revealed a tear that measured 12 mm in the short axis and 10 mm in the long axis, affecting nearly half of the fascia's thickness. Following this, I was referred to a podiatrist who advised me to avoid putting any weight on my foot and scheduled another ultrasound in six weeks. She mentioned that the tear needed to heal by at least 30% before I could start putting weight on it again. If the progress was satisfactory, she suggested a graduated reintroduction of weight over the subsequent weeks: starting at 25% for two weeks, then moving to 50%, and so on, with further physiotherapy likely needed after that period. Fast forward six weeks, I underwent another ultrasound that indicated my injury had improved to an 8 mm short axis and 17 mm long axis tear, now involving less than half of the tendon’s thickness. However, when I finally managed to see the podiatrist two weeks later, she seemed to misremember our previous conversation, insisting that I had been using a walking boot, which I had actually never owned. This misunderstanding led her to appear critical when I explained why I hadn’t begun to put weight on my foot yet, stating she had advised against it until our next meeting. She expressed concern about my leg losing strength due to inactivity and informed me that I would need to be fully weight-bearing at our next appointment, regardless of the tear's condition. If I wasn't ready by then, she indicated uncertainty about how to proceed. Now, I'm left wondering if I should seek a second opinion. Her inconsistent guidance is causing me a lot of stress, and my previous experiences with healthcare providers haven’t been great. This situation is adding to my list of challenging interactions with doctors and I'm not sure how to move forward.

Is My Eardrum Infected?

I'm a 25-year-old man, standing 6'1", and lately I've been experiencing pain in my right ear. In an attempt to identify the source of the discomfort, I purchased a device designed to remove earwax. Additionally, I've been dealing with swollen occipital lymph nodes, which have been around 1 cm in size for the past year. I received feedback from ChatGPT, indicating that my eardrum may appear infected, but I'm somewhat skeptical about that assessment. Any advice would be appreciated!

Concerns Regarding Endometrial Polyps

For the last couple of months, my menstrual cycles have been unusually prolonged, often extending for two weeks at a time. Recently, I've experienced irregular bleeding patterns, where some days I have bleeding and other days I do not, which feels quite unusual for me. To address my concerns, I consulted with my physician, who recommended that I undergo a transvaginal sonogram (TVS). The results revealed an echogenic mass in the endocervical canal, measuring 1.81 x 1.51 x 1.88 cm, with a total volume of 2.7 cc. Is this something I should be anxious about? Thank you in advance for your insights.
