Identifying the Red Spots on My Baby

8/6/2025, 6:00:43 PMMale25-34

I’m concerned about the appearance of red spots on my four-month-old daughter’s arms, particularly around her wrists and calves. These spots emerged just yesterday. She doesn’t seem distressed by them, and they don’t appear to be raised very much, if at all. I doubt it's heat rash since she has mostly been in a climate-controlled setting, with only brief moments of exposure to heat, such as when I take our dog outside. Additionally, we relocated to a new apartment about a month ago, but all our belongings were thoroughly cleaned prior to the move, and I maintain a tidy living space. Although we've recently introduced our dog into the home, my daughter generally has normal skin, without a history of sensitivity. I am puzzled about the nature of these spots. If you have any questions that could assist in forming a theory about this, please feel free to inquire! ### Baby's Details - **Age:** 4 months - **Sex:** Female - **Height:** 21 inches - **Weight:** 10 lbs - **Ethnicity:** Caucasian - **Location:** Northeast Missouri - **Diet:** Possibly lactose intolerant; currently on a soy-based formula - **Medications:** None I attempted to upload a picture for reference, but unfortunately, it didn’t work out.

It's understandable to be concerned about new red spots on your baby's skin, especially since they're a recent development. Based on your description, red spots in infants can have various causes, including allergic reactions, mild skin irritations, or even insect bites. Given that your daughter does not seem distressed and the spots are not raised, while this may lessen the concern for something serious, monitoring is still important.

Explanation:

  1. Possible Causes: The red spots could be linked to:

    • Irritation or Allergic Reaction: New items in your home, like pet dander from the dog, or even new soaps, detergents, or fabric materials can sometimes cause skin reactions.
    • Mild Insect Bites: Bites from mosquitoes or other insects can create localized red spots that typically don't cause much discomfort.
    • Dermatitis or Eczema: A common skin condition in infants that may present as red spots or patches, especially in areas where skin may rub against clothing.
  2. Signs to Monitor: It’s important to observe the spots and how they change over time. Key indicators include:

    • If they worsen, grow in size, or spread.
    • If new spots appear.
    • If your daughter develops any additional symptoms like fever, excessive fussiness, or changes in eating or sleeping patterns.

Next Steps:

  1. Observe the Spots: Keep an eye on the spots for the next few days. Take note of any changes in their appearance or any other symptoms your daughter may develop.

  2. Maintain a Diary: Record when the spots appeared, any potential exposure to new items, and any changes in your environment or your daughter’s routine, such as increased pet interaction.

  3. Gentle Care: Ensure your daughter’s skin remains clean and moisturized. Use mild, fragrance-free soaps and avoid any new products that might irritate her skin further.

  4. Limit Exposure: Temporarily reduce your dog’s interaction with your daughter to see if the spots diminish after a few days, which can help identify if they're allergy-related.

  5. Document Changes: If the spots do not resolve in a week, worsen, or your daughter displays any distress, gather the observations you've documented and seek advice from a healthcare professional.

Your prompt attention and observance are commendable. Trust your instincts as a parent, and take action based on what feels right for your daughter’s health. Please feel free to ask more questions or seek further guidance if needed.

Temporary Ridges on the Scalp When Under Stress

I’ve recently observed the emergence of distinct ridges on my scalp, which appear exclusively during periods of intense stress. These ridges seem to correlate with an increase in blood pressure. I can identify 3 to 4 prominent ridges that stretch from the front to the back of my head. Each ridge measures approximately 0.25 to 0.5 inches in height and spans about 3 to 5 inches in length. They are quite conspicuous, as they can be both seen and felt distinctly. Typically, these ridges last around 30 minutes during significant stress, but they vanish completely afterward. I am curious if anyone else has experienced something similar or knows what could be causing this phenomenon. My attempts to research online have mostly led me to results discussing persistent conditions, such as skull fractures or thickening of the scalp, rather than addressing these fleeting ridges that only occur occasionally.

Assessing Facial Swelling: When to Seek Help

I am a 36-year-old woman, standing at 5'6" and currently weighing 135 pounds. Just yesterday, I underwent an extraction of my upper right back molar, which shattered during the procedure (my dentist may have referred to it as tooth number 1). I'm currently prescribed clindamycin three times daily to combat an infection, along with Norco 5 as needed for pain management. I have a follow-up appointment scheduled for tomorrow to evaluate my healing process. However, I'm concerned about the swelling in my face. Should I head to the emergency room, or is it possible for my dentist to fit me in for a visit this afternoon?

Could This Be Ringworm?

For over a month now, I've had a rash on my left thumb, specifically the F32 area. I first observed it when it was roughly the diameter of a pencil eraser. Interestingly, I just resumed taking Zoloft and Wellbutrin about a week ago; however, the rash had already made its appearance prior to starting these medications.

Should I Visit the ER or Urgent Care for Blood in My Stool?

I’m a 27-year-old man currently taking finasteride (1 mg) and amoxicillin (500 mg). Recently, I’ve noticed intermittent occurrences of maroon blood in my stool, which have become more frequent over the last couple of weeks. Additionally, I’ve been feeling a burning or stinging pain in my lower left abdomen that fluctuates, registering around 4 to 5 on a discomfort scale. Just yesterday and again today, my stools exhibited dark maroon streaks. I have a gastroenterologist appointment scheduled for Monday, but I’m wondering if I should seek immediate care at the ER or an urgent care facility before then. I’m uncertain whether it’s safe to hold off until my appointment or if I should get evaluated sooner. I appreciate any guidance you can offer. Thank you!

Concerns Regarding Surgical Site Appearance

Are there any surgeons among us? I’m a 36-year-old man, measuring 5 feet 5 inches tall and weighing 125 pounds. I underwent ulnar nerve release surgery at my wrist on July 18th and attended a follow-up appointment with my surgeon's physician assistant (PA) yesterday, August 5th. During the visit, the PA informed me that everything appeared to be healing well and that I had no limitations. However, the following day, I noticed that the incision seems excessively open, even though there’s no bleeding or discharge present. What concerns me is the presence of some white material in the center of the incision. Should I reach out to my doctor just a day after my appointment, or is this appearance typical during the healing process? I wonder if the open area at the top of the incision will eventually close as recovery continues. The PA applied steri-strips, which I am to wear for another week before commencing physical therapy, where I will massage the incision to minimize scar tissue, and I have been diligent about keeping them on. I would appreciate any insights! Thanks!
