Dog Bite Treatment: Tetanus Shot and Antibiotics for Recovery - Dermatology

If bitten by a dog, it is important to receive a tetanus shot and take antibiotics?


I would like to ask the doctor, I was bitten on the calf by a stray dog on April 10.
The wound is not large, and I went to the emergency room to receive a tetanus shot and took antibiotics for three days.
Currently, the appearance of my calf looks fine, but it still hurts when pressed, and it feels hard inside.
I am not sure what is going on.
Is it a bruise or something else? Thank you!

No lesions were observed, making it difficult to determine the issue.
If it is causing significant distress, please seek medical attention as soon as possible; either a dermatologist or a surgeon would be appropriate.

When it comes to treating dog bites, especially those from stray dogs, it’s crucial to take the situation seriously due to the potential risk of infection and rabies. In your case, it sounds like you have already taken the appropriate initial steps by visiting the emergency room, receiving a tetanus shot, and starting a course of antibiotics. However, you are still experiencing pain and a sensation of hardness in the area, which raises some important considerations.

First, let’s address the pain and hardness you are feeling in your calf. After a dog bite, it is not uncommon for the area to remain tender and swollen for some time, even if the external appearance seems normal. The hardness you are feeling could be due to several factors:
1. Localized Swelling: After an injury, the body responds with inflammation, which can lead to localized swelling. This swelling can create a firm feeling in the tissue, especially if there was any trauma to the underlying muscles or connective tissue.

2. Bruising: If the bite caused any bruising, the area may feel hard as the blood collects under the skin. Bruises can take time to resolve, and the hardness may persist until the body reabsorbs the blood.

3. Infection: While you are on antibiotics, it’s important to monitor for signs of infection. Symptoms of infection can include increased redness, warmth, swelling, and discharge from the wound. If you notice any of these signs, it’s crucial to follow up with your healthcare provider.

4. Hematoma: If there was significant trauma to the area, a hematoma (a localized collection of blood outside of blood vessels) could form, leading to a hard lump. This can also cause pain and may take time to resolve.

5. Muscle Strain: Depending on how you reacted during the incident or how you have been moving since the bite, you may have strained a muscle in the area, contributing to the pain and hardness.

Given that you have already received medical treatment, it’s advisable to keep monitoring the wound and your symptoms. If the pain persists or worsens, or if you develop any new symptoms, you should return to your healthcare provider for further evaluation. They may want to perform an examination to rule out any complications, such as an abscess or deeper tissue injury.

In terms of recovery, here are some general recommendations:
- Rest: Avoid putting too much pressure on the affected leg to allow healing.

- Ice: Applying ice packs to the area can help reduce swelling and alleviate pain. Just be sure to wrap the ice in a cloth to protect your skin.

- Elevation: Keeping your leg elevated can help reduce swelling.

- Pain Management: Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help manage pain, but consult your doctor before taking any medication.

Lastly, ensure you complete the full course of antibiotics as prescribed, even if you start to feel better. This is important to prevent any potential infection from developing.

In summary, while it’s good that you’ve taken the necessary steps after the dog bite, the ongoing pain and hardness in your calf warrant close monitoring. If symptoms persist or worsen, don’t hesitate to seek further medical advice. Your health and recovery are the top priority.
