Swimming with Minor Cuts: What You Should Know
I'm a 19-year-old male, standing at 5'4" and weighing 135 pounds, and as far as I'm aware, I don't have any underlying immune system issues. I’ve been looking forward to a trip to the lake with friends for several months. However, during a run last weekend, I tripped on some pavement and scraped my shoulder. The resulting cut is approximately 3-4 inches long and about a third of an inch wide. Thankfully, it’s relatively shallow and mostly healing with a scab forming. With only two days left before our departure to Lake Ontario, I can’t help but feel anxious about the possibility of infection. Although I’m considering using waterproof bandages, I worry about whether I can find one that will stay secure. Is the scab sufficiently protective against infection? Should I take additional precautions, or would it be best not to swim at all?

It's great that you're looking forward to your trip, and it's understandable to feel anxious about your cut. Here’s what you need to know about swimming with minor cuts and how to keep yourself safe while having fun.
Main Points
- Scab Protection: A formed scab on your cut is a good sign as it provides some natural protection against bacteria.
- Swimming Precautions: While swimming with a minor cut can be okay, it's essential to take some precautions to reduce the risk of infection.
Explanation
A scab indicates that your skin is healing and is likely to offer some protection from infection. However, cuts, even when they have scabs, can still be vulnerable when exposed to water, especially in natural bodies like lakes where bacteria could be present.
Next Steps
-
Waterproof Bandage: Use a high-quality waterproof bandage to cover the cut. Make sure it adheres well; look for products designed specifically for waterproof protection to ensure it stays on while swimming. Change the bandage before swimming if it gets wet.
-
Monitor the Cut: Keep an eye on the cut for any signs of infection, such as increased redness, swelling, pus, or if you develop a fever. If you notice these symptoms, it's best to avoid swimming and protect the area until it heals.
-
Limit Exposure: If you decide to swim, try to minimize the amount of time your arm and the cut are submerged, especially if you feel uncomfortable about it.
-
Post-Swim Care: After swimming, rinse the area with clean water and gently pat it dry. You can apply a fresh waterproof bandage afterward.
-
Enjoy Responsibly: If it makes you anxious, trust your instincts. Relaxing with your friends without swimming may also be a fun option.
Following these steps should help you enjoy your trip while keeping your cut protected. Have a great time at Lake Ontario!

Long-lasting Red Bumps on Chest - Seeking Advice
Hello everyone, I’m a 24-year-old male, and for more than a year, I’ve been noticing numerous red, bump-like formations on my chest. While they don’t cause me any pain, itching, or discharge, I’m concerned because they persist and maintain a red or slightly inflamed appearance. Despite trying various over-the-counter acne medications and creams, there hasn’t been any improvement; they haven’t diminished in size or faded away, and they don’t react sensitively when touched. Currently, I’m unable to visit a dermatologist, so I’m reaching out to see if anyone else has encountered similar issues or might have suggestions on what these could be. Could they possibly be cysts, keloids, acne scars, or something more serious? I appreciate any feedback or advice you might have. Thank you!
Blood Donation and Finasteride Usage
Several months back, my dermatologist prescribed me a daily dosage of 1mg of Finasteride. Approximately six weeks later, I chose to donate blood at a nearby blood donation center. I either missed the query regarding this medication on the form or it simply wasn’t included. Today, as I headed to donate blood once more, this time with the American Red Cross, I found that they list Finasteride among the medications that disqualify an individual from donating. This is due to the potential risk it poses of causing birth defects in males if a pregnant woman were to receive the blood. How significant was my oversight? I feel deeply regretful for not catching this detail earlier…
