Pain and Difficulty Bending Finger After Rusty Needle Injury: When to Seek Help?

Stabbed my finger with a metal needle, and the next day it was difficult to bend?

Hello, I was punctured near the first joint of my index finger by a rusty iron needle yesterday.
I cleaned the wound and applied Mentholatum right after, and aside from bleeding, there was no other pain.
The wound is about 0.5 centimeters in size.
However, this morning I experienced pain when bending my finger.
Should I seek medical treatment for this situation? Thank you.

Hello! Please visit the general surgery department as soon as possible.
Do not let the wound come into contact with tap water, and do not apply Mentholatum.
You need to get a tetanus shot.
Take care! Changhua Hospital is concerned about you!

More Info

In the case of a rusty needle injury to your finger, it is crucial to take the situation seriously, especially since you are experiencing pain and difficulty bending the finger after the initial injury. Rusty objects can introduce bacteria and other pathogens into the body, increasing the risk of infections, including tetanus, which can be life-threatening if not treated promptly.

Given that you have already experienced bleeding and now have pain when trying to bend your finger, it is advisable to seek medical attention as soon as possible. Here are several reasons why you should see a healthcare professional:
1. Infection Risk: Even if the wound seems small (0.5 cm), the risk of infection from a rusty needle is significant. Bacteria can enter through the skin and cause localized infections, which may lead to more severe complications if not treated. Signs of infection include increased redness, swelling, warmth around the wound, and pus or discharge.

2. Tetanus Prophylaxis: Tetanus is a serious bacterial infection that affects the nervous system and can lead to muscle stiffness and spasms. If you have not had a tetanus booster in the last five years, or if you are unsure of your vaccination status, it is essential to get a booster shot. The healthcare provider will assess your vaccination history and determine if you need a tetanus shot.

3. Assessment of Injury: A healthcare professional can evaluate the extent of your injury. They will check for any deeper damage to the tendons, ligaments, or nerves that may not be immediately apparent. If there is any concern about the injury, they may recommend imaging studies, such as an X-ray, to rule out fractures or other complications.

4. Pain Management: If you are experiencing pain, a doctor can provide appropriate pain management strategies. This may include prescribing pain relief medications or recommending over-the-counter options. They can also advise on how to care for the wound to minimize discomfort.

5. Wound Care: Proper wound care is essential to promote healing and prevent infection. A healthcare provider can clean the wound thoroughly and provide instructions on how to care for it at home. They may also apply a sterile dressing to protect the area.

6. Physical Therapy: If you continue to have difficulty bending your finger after the initial healing phase, a healthcare provider may refer you to physical therapy. A physical therapist can help you regain strength and flexibility in your finger through targeted exercises.

In summary, given the nature of your injury and the symptoms you are experiencing, it is highly recommended that you seek medical attention promptly. Do not wait for the pain to worsen or for additional symptoms to develop. Early intervention can prevent complications and ensure that your finger heals properly, allowing you to regain full function. Remember, it is always better to err on the side of caution when it comes to injuries involving potential exposure to rust or other contaminants.
