When to See a Doctor for a Cut

by James Hubbard, M.D., M.P.H.

When to see a doctor for a cut?

Crash. A brick flies through a window. Your spouse is cut and bleeding, but otherwise unhurt. The streets are jammed with rioters. There’s no ambulance available, and even if you could get to the hospital, it’s packed.  Should you fight the crowd or stay put? The urgency of when to see a doctor for a cut depends on several things.

There’s not much you can do with the following wounds except to stop the bleeding and get to a doctor as soon as possible:

  • Cuts that have punctured the abdominal cavity (because of the risk of unseen bleeding and extreme likelihood of serious infections).
  • Neck wounds with profuse bleeding or that include the airway.
  • Cuts of a major artery. (The blood usually spurts, and the tissue distal to the wound becomes cool and dark.) If the artery is not surgically reconnected within hours, the tissue dies due to lack of blood supply. After that, the dead tissue needs a surgical amputation, or it’s sure to get infected, and the infection is sure to spread into the healthy flesh and the bloodstream. You can get very sick and even die.

Other cuts are less urgent, but are at high risk for infection. In the following situations, clean the cut well, and consider taking an antibiotic, or at least use an antibiotic ointment. Then, try to see a doctor within a day or two.

  • You have diabetes or certain other chronic diseases. (You heal slower, and your wounds are more likely to get infected.)
  • The tissue around your cut, however small, becomes swollen, more tender, or more red, or the cut oozes a cloudy pus.
  • You think the injury has involved the bone. You want to prevent a bone infection if at all possible. It’s much harder to treat and can cause serious damage.
  • You can’t clean the wound adequately because it’s too deep, grimy, or painful.
  • You haven’t had a tetanus shot within ten years.

Some cuts injure more than just skin. See a doctor within as few days, if possible, if:

  • There’s numbness distally (on the side farthest from the heart). You may have cut a nerve that needs repair.
  • You’ve lost joint range of motion. You may have cut a tendon that needs repair.

Hope these tips help. I welcome comments and questions.

    Thank you! That’s what I was thinking too. I wonder if I didn’t damage something in my ankle.

    I cut the inside my ankle by dropping a butcher knife on it. The cut was small, less than half an inch long but it was gaping. It didn’t bleed much. I cleaned the wound with warm running water, dried it, applied two steri strips and antibiotic ointment and covered it with a bandaid. Shortly after it happened, my ankle started hurtin when I stepped down on my foot. Now my ankle is swollen above and below the cut. I have a blood clotting disorder and I’m on blood thinners. Is this something that should be looked at by my doctor?

      Sounds like it.

    I sliced off about a 1/4 of a dime’s worth of flesh from my left index finger at the top, next to the fingernail. I was able to stop the bleeding by applying pressure on the wound with some paper towels. I’ve been keeping the wound covered with anti biotic ointment, but I’m still wondering whether or not I should see a doctor. There’s no blood flow but it’s a fairly deep cut and it looks like blood is sitting on the inside of the wound. There’s no serious pain and no blood coming through the bandaging, but I’m concerned about the size with infections and whether or not I need stitches (or if it’s even possible- it’s a wide cut).

      If you’re not sure, then you should see your doctor. Perhaps ask at the front desk could anyone take a look at it and see if needs to be formally seen.

    I cut the tip of my thumb through the nail and into a bit of flesh. I stopped it from bleeding after 4 mins of running under running water. I went to a local pharmacy and they gave me merbromin solution and some gauze. Now tge thing is it doesnt hurt much or anything but there are dried blood formation under the nail and the flesh cut. Both flesh and nail fully intact but im just worried it may worsen if i dont get it checked. Should i be worried? Abd u havnt hot a tetanous shot in more than 10 years. Also i got cut whir handling raw pork

      Sounds like you’re due for a tetanus shot. Whether you should otherwise be worried, I wouldn’t know without an exam. However, generally speaking, if you’re worried, have it checked.

    My cat recently scratched me when it was running from our neighbor’s dogs. Most of the wounds are superficial but I do have a puncture wound to my middle finger past the DIP joint. My concern is that there is a skin flap that overlies the wound bed and I can’t completely visualize it even when I manage to move the flap to the side. I’ve already been to the ER and been prescribed Augmentin, so I’m not too concerned about infection. My question is will the wound heal even if unviable tissue overlies the wound bed? Also, is it possible that tiny debris would prevent proper healing of the injury?

    • http://thesurvivaldoctor.com/ James Hubbard, MD, MPH

      In general, tiny debris could be a cause of infection, not delayed healing. If a flap of skin dies on top of the wound, the flap will eventually come off on its own or with your help. Unless really deep, the wound will heal from underneath. If you have problems or concerns, you should follow up with your regular doctor.

        Thank you very much for your time and answers!

          You’re welcome.

    I was working in my garden with manure 2 days ago. I got a small cut on my elbow. I woke this morning and released the cut was a bit red and tender. The nodes in my armpit feel a bit tender and swollen. I pulled the scab off and applied antibiotic ointment. Should I see a Dr. for antibiotics. I’m a bit vague on when my last tetanus shot was.

    i cut my thumb opening a canned ham. It bled for a long time.I believe the bleeding has stopped but my hand is turning black and blue in between 2 veins
    . Should I be concerned?

    • http://thesurvivaldoctor.com/ James Hubbard, MD, MPH

      I can’t really tell you that without an exam. It would depend on the depend on the depth, length, and what exactly you cut. In general, a small bit of the hand turning black and blue would just be the blood that’s seeped into the tissues of the hand. Of course, if it’s cold and closer to the tip than the wound is, it could be a damaged artery and that would be serious.

  • lynne23

    I think it will be fine. The feeling is coming back in my arm and elbow area. Thank you.

  • lynne23

    Thanks. If there were nerve damage how quickly should I get it looked at?

    • http://thesurvivaldoctor.com/ James Hubbard, MD, MPH

      Typically nerves can be repaired within a few days of injury.

  • lynne23

    Some dishes fell into my sink and as i was removing them a knife standing straight up went into my hand.towards the pinky in my palm. The cut is almost 1/2 inch long and maybe as deep. My husband cleaned it and superglued it, but i wonder if i should get it checked out.

    • http://thesurvivaldoctor.com/ James Hubbard, MD, MPH

      It’s your call. I do have a video on assessing a cut that might give you a little more information. But it won’t make the decision for you. http://www.thesurvivaldoctor.com/2011/11/16/video-how-to-assess-and-clean-a-cut/

    • http://thesurvivaldoctor.com/ James Hubbard, MD, MPH

      I can’t answer that for you, individually, without examining it. In general, if the cut looks like it might open up because it’s over a joint would be a reason. Or you’re having trouble moving a finger, you might have damaged a tendon. Because of sweat, glue or tape doesn’t stick as well on the hand. Picture how it would look if it opened back up. Would it be wide enough not to heal well? One other thing. If it starts looking more than a little red or looks in any other way like it’s getting infected, see a doctor to start on some antibiotics.
