Child Accidentally Injures Thumb While Snacking

2/17/2026, 6:20:21 AMMale25-34

While enjoying a snack, my 6-year-old inadvertently bit down on the pad of his thumb, breaking the skin and causing it to bleed for a couple of minutes. To treat it, I rinsed the area with warm, soapy water, then applied a triple antibiotic ointment, and sealed it with a bandage. However, the wound appeared somewhat closed at the surface, leaving me uncertain about how effectively the soap and antibiotic could penetrate the area. Since he hadn’t brushed his teeth for a while—having just had a snack before his nighttime routine—I'm aware that human bites can carry a significant risk of infection. How worried should I be about this incident? Is there a need for preventive antibiotics, or is it sufficient to monitor for any signs of infection?

In this situation, your main concern is ensuring that your child’s thumb injury does not become infected, especially since human bites can lead to infections due to bacteria in the mouth. You’ve taken appropriate initial steps, including cleaning the wound and applying an antibiotic ointment, which is excellent.

Explanation

When a wound occurs, especially one caused by biting, there is a potential risk for infection due to bacteria entering the broken skin. In your case, the fact that you’ve cleaned the wound and applied ointment is helpful. The risk of significant infection from a minor bite is generally low, especially if you actively monitor the wound. Most bites like this will heal well without complications.

Next Steps

  1. Monitor the Wound: Keep an eye on the injury over the next few days. Look for signs of infection, such as increased redness, swelling, warmth, or pus. If your child develops a fever, it may also indicate infection.

  2. Keep it Clean: Continue to clean the area gently twice a day with warm, soapy water. After rinsing, reapply the antibiotic ointment and cover it with a clean bandage. This will help keep the wound protected.

  3. Avoid Irritants: Ensure that your child avoids putting their thumb in their mouth or any other dirty environments to prevent introducing new bacteria.

  4. Days to Watch: If the area does not improve or if you see signs of infection within the next few days, check in with a healthcare professional for further evaluation.

  5. Brushing Teeth: After meals, encourage your child to brush their teeth before bed—this reduces the bacteria in their mouth, which could be a factor in infections.

Preventive antibiotics are usually not necessary for small clean bites unless there are complicating factors like extensive swelling, altered immune function, or other significant risks presented.

It sounds like you’re doing a great job caring for the wound, and continuing to monitor it closely should help. If you have further concerns, don’t hesitate to reach out for more information.

Concerns After Accidental Exposure to Cleaning Products

I’m a 22-year-old woman, standing at 6 feet tall and weighing 170 pounds. I don’t smoke and I have a history of eczema and TMD (temporomandibular disorders). I accidentally exposed myself to bleach and cleaning chemicals while taking a shower. Here’s what happened: Earlier, my roommate had been cleaning some mats in the shower with bleach and possibly other cleaners like Lysol or Fabuloso – I'm not entirely sure what she used. Unfortunately, she got some of that on my shower loofah, which I didn’t realize since I’m currently unwell and couldn’t detect the odor before applying soap to it. Now I’m feeling quite anxious about it. My skin has a bleach scent, but I don’t feel any pain or discomfort. Everything seems normal, yet I can’t help but worry. Am I in the clear?

Special Offer: Purchase 5 Venous Procedures, Receive 2 Arterial Pre-Op Free

Approximately a month ago, I underwent a minor foot surgery, but the experience was quite challenging due to multiple intravenous (IV) catheter placements that took a staggering seven attempts. It was an exhausting day, and I’m trying to sort through it all in retrospect. Usually, I’m not the hardest person to stick, and I typically manage failed attempts well; my previous record was just three tries. Initially, the medical staff attempted to insert the IV on the back of my left hand, followed by my inner forearm, but without success. Despite the frustrations, we shared some laughter and I admitted my lack of hydration might have contributed. Eventually, another nurse tried accessing my wrist, which also didn’t work out. We then shifted our focus to the right hand, where the experience was significantly more painful. I noticed bright blood and could even see my heartbeat in the tube, so we decided to move up my arm. After five attempts, one catheter finally pierced through, but after a slight retreat, it seemed to wiggle painfully inside, causing me to squirm in discomfort. The nurse managed to administer medication quickly but mentioned she encountered "a lot of resistance." Concerned, she asked the first nurse if it was something serious. They later returned with a more experienced nurse who confirmed, “yes, that’s bleeding,” and began to massage a significant ball of blood in my upper inner arm, reducing it from the size of a lemon to that of a walnut while applying pressure below. I felt faint and experienced involuntary spasms during this ordeal. The anesthesia team eventually decided to place the IV in the operating room under nitrous oxide. Once the nitrous oxide was administered, I experienced a sensation akin to breathlessness but settled into a relaxed state, after which everything went dark. In that brief moment, I perceived a repetitive voice and felt the familiar sensation of alcohol wipes followed by two more IV attempts. It was quite a surreal experience! The surgical procedure itself was successful, as per the notes, it took two attempts to place the IV using an ultrasound in the OR. Now, I’m concerned about the lingering pain in my arm. It’s not unbearable, but I find myself wincing occasionally and struggling to roll onto that side while sleeping at night. Should I endure this for another month before inquiring about potential remedies? Additionally, I’m experiencing ongoing mental fog and headaches. I’ve never faced issues with general anesthesia before, yet this recovery has been rather unusual for me. Any advice would be appreciated!

Experiencing Chest Pain and Rapid Heartbeat Upon Waking: Seeking Advice

Greetings, I'm a 20-year-old female and have been diagnosed with an indeterminate autoimmune condition, though I'm unsure if that's connected to my current issues. Recently, I've noticed a significant discomfort in my sternum every time I wake up, making movement quite difficult. I suspect this pain arises from hunching my shoulders during sleep since it intensifies when I try to stretch them apart. It's been quite bothersome, and after consulting with an ER professional earlier on, I was advised to use naproxen. Unfortunately, this medication hasn’t provided much relief. What’s increasingly alarming is that alongside this discomfort in the center of my chest, I now also feel pain on the upper left side of my ribs coupled with a racing heartbeat and shortness of breath every morning. This has been occurring nearly every day for about three weeks. Since these symptoms are persistent but I am still managing to get by, I’m uncertain about when it’s appropriate to seek further medical evaluation and what I should do in the interim. My doctor's office has availability only months down the road, and visiting is quite a hassle. Given that I’m not in a life-threatening situation, I hesitate to go to urgent care or the hospital. I’m looking for advice on the next steps and whether my concerns warrant immediate attention. Thank you for any support you can offer!

Concerns Regarding Epidural Complications

Hello everyone, I'm reaching out for guidance. My partner, who is just 18 years old, recently underwent an epidural procedure using Rapivacaine (Norpo). I’m uncertain about the exact dosage administered. The nurse mentioned that a machine regulated the dosage, but I'm skeptical about that information. Now, 2-3 days post-procedure, she is still experiencing numbness! The thigh of her left leg is almost entirely numb; it’s barely functional and she struggles to move her feet and toes on that side. On her right side, there’s slight improvement—although there remains some numbness in her thigh and leg, it’s significantly more functional compared to her left leg. Is there anyone who can offer insights? We are still here with unanswered questions, as the doctors and nurses seem baffled and unsure of how to respond.

Seeking Insight on Recent Health Concerns

Greetings, everyone! This is my inaugural post on Reddit, and I find it necessary to address a serious matter. I'm a 19-year-old woman experiencing convulsions in my mid-abdomen and middle back that have persisted for the last three to five days. I initially dismissed it as my own tendency to be dramatic, but the issue shows no signs of resolving. Additionally, I've noted a decline in my memory over the past several days, potentially extending to weeks or months. I’ve dealt with anorexia nervosa for over a year, but I’ve made significant progress and currently maintain a healthy body mass index. However, I've also struggled with generalized anxiety disorder since I was 11. Lately, my anxiety has skyrocketed, and I'm starting to feel the physical repercussions. Though I’ve been in therapy for several months, I regret to say that my discussions have made my counselor uncomfortable—something I completely understand, given the sensitive nature of the topic, and I feel genuinely distressed about this. On a side note, I've increased my physical activity, including sit-ups, walking, and biking, so I am curious if these convulsions could be related to muscle spasms. If that is the case, why are they specifically concentrated in my torso? I welcome any suggestions or feedback, and please let me know if more details are required. Thank you!
