Concern After Mouse Bite?

8/9/2025, 1:00:46 AMMale25-34

Hello everyone, I’m a 21-year-old female, standing 162 cm tall and weighing 44 kg, without any current medications or health concerns. Today, I had an encounter with a rather feisty lab mouse that resulted in a bite. The mouse punctured my glove, leaving a small wound on the tip of my pinky finger. Initially, it bled a fair amount, so I quickly rinsed it under running water and applied 70% alcohol several times for disinfection. The injury has since diminished, barely visible now, with just a slight reddening compared to my other fingers. It's been about an hour, and although there's slight tenderness (with a pain level around 5-7), it does feel warm, though not excessively so. In addition, I've noted a peculiar sensation that resembles numbness, though I'm unable to pinpoint it exactly. I considered sharing a photo to provide clarity, but the wound is quite small and might not show well. Just to clarify, the mouse was healthy, and in case it had any issues, the most serious would be multiple myeloma, which I understand isn’t an immediate concern regarding infections. I’ve received reassurance from others that I’ll be fine, but I can’t shake off my worries. Any advice or thoughts? Thank you!

It's understandable to feel concerned after a mouse bite, especially with your symptoms. While the risk of serious infection from a healthy lab mouse is low, there are still steps you should take to ensure proper care and monitor your wound.

Main Points:

  • Clean the wound thoroughly and monitor for changes.
  • Watch for signs of infection or worsening symptoms.
  • Avoid further irritation to the area.

Explanation:

Mouse bites can be concerning due to the potential for bacterial infection, even from household rodents. The fact that you rinsed the wound and used alcohol is a good first step for disinfection. The warmth and tenderness you're experiencing can be normal following a bite, but numbness is worth paying attention to.

Next Steps:

  1. Monitor the Wound:

    • Keep an eye on the wound for any signs of infection over the next few days. Look for increased redness, swelling, pus, or if the pain escalates.
  2. Pain Management:

    • For the tenderness, you can take over-the-counter pain relief (like ibuprofen or acetaminophen) as directed if you feel it's necessary.
  3. Keep the Area Clean:

    • Continue to clean the area gently with soap and water daily, and you may want to apply a topical antibiotic ointment (like Neosporin) to prevent infection.
  4. Avoid Irritation:

    • Try to keep the area protected from further injury or irritation, perhaps by avoiding tight gloves or jewelry on that finger.
  5. Watch for Symptoms:

    • In the coming days, monitor for any new developments such as increased numbness, changes in sensation, or symptoms that suggest a growing infection.
  6. Seek Help if Necessary:

    • If you notice signs of infection or if the numbness worsens or persists beyond a few days, consider following up with a healthcare provider for an evaluation.

Remember, feelings of anxiety are normal after an incident like this, but staying calm and observing the wound can help put your mind at ease. Feel free to update if your symptoms change or if you have more questions.

Intense Pain in Left Thumb

Greetings, I’ve been experiencing a piercing pain at the tip of my left thumb intermittently. This discomfort is situated within the thumb rather than on the outer skin. It primarily affects the underside of the thumb and surrounds the base of the nail. The pain seems to extend only to the first skin fold, specifically around the distal phalanx. When applying pressure, I’ve noticed some red streaks appearing beneath the surface, alongside the white area. I trust this explanation is clear. This issue has persisted for over a year, occurring sporadically but intensifying as time has passed. Could this be a cause for concern? A bit about myself: I am a 25-year-old female with no significant medical issues in my background. I previously smoked cigarettes for three years, transitioned to vaping, and have been vaping for six years now. I maintain an active lifestyle, frequently going to the gym and participating in various sports such as indoor football and pickleball. I don’t have any known allergies.

Resources for Safe Mouse Cleanup

While it may not be a typical inquiry for a healthcare professional, I find myself in need of guidance. Recently, we had an uninvited mouse visitor in our home, and unfortunately, it left droppings in my children's toy storage and on the changing table. I am seeking advice on how to effectively disinfect all affected items or determine if disposal is necessary to prevent any health risks. My children are quite young, at 2.5 years and just 4 months old. If they’ve potentially been exposed to mouse droppings, should I reach out to their pediatrician? For reference, I’m a 32-year-old female, standing at 5'6" and weighing 140 pounds, not currently on any medications.

Excessive Electrical Shocks Encountered

Hello everyone! This is my inaugural post here since I don't frequently use Reddit. I'm a 15-year-old male, and I've recently been experiencing an unusual frequency of electrical shocks. Whenever I come into contact with anything that is either highly charged or conductive, I receive a sharp, irritating jolt. This situation has become increasingly bothersome. For instance, I can only grasp my Mac charger by the cord and not the plug itself. I'm curious if anyone has insights into why this is happening. Please let me know; I hope it's nothing serious! 💕
