Why Does My Arm Hurt After A Shot?

Experiencing arm pain after a shot is common and usually not a cause for concern. Understanding why your arm might hurt, what to watch for, and how to alleviate discomfort is important. While some vaccines tend to cause more pain, there are tips to prevent it.

If you suspect you are experiencing a serious reaction after a shot, consult a vaccine injury attorney to learn about your legal options.

Causes of Post-Vaccination Arm Pain

After you get a shot, your arm might hurt for a few reasons, which may include:

• The needle: When the needle goes into your arm, it can cause a little damage to the muscles and tissues. This is normal and usually heals quickly.
• Your body’s response: Your immune system (the part of your body that fights off germs) starts working when you get a vaccine. This can cause some swelling and soreness in your arm.
• The vaccine itself: Some vaccines have ingredients that can irritate your arm a bit. This is also normal and usually goes away soon.
• Tension: If you’re nervous about getting a shot and tense up your arm muscles, it might hurt more afterward.

Recognizing Serious Vaccine Complications

Most of the time, arm pain after a shot is not serious. But it’s good to know what to look out for, just in case.

How long should your arm be sore after a shot? Usually, the pain should start to get better after a day or two. Most people feel fine within a few days. If your arm still hurts a lot after a week, you might want to talk to a doctor.

Here are some signs that you should talk to a doctor sooner:

• Very bad pain that doesn’t get better with pain medicine
• A lot of swelling, redness, or warmth around where you got the shot
• Fever, chills, or feeling very sick
• Trouble moving your arm
• A rash or itching all over your body

Which Vaccines Cause the Most Pain?

Some shots tend to hurt more than others.

Here are a few that people often say are more painful:

• Tetanus shots, which can cause more soreness because the vaccine is a bit thicker. Sometimes, this can lead to increased arm pain and stiffness. Despite the discomfort, tetanus shots are essential for preventing tetanus, a serious bacterial infection.
• HPV vaccine often causes more arm pain but is crucial for preventing human papillomavirus (HPV), which can lead to certain types of cancer, including cervical, anal, and throat cancers. The temporary pain is a small price to pay for the significant long-term health benefits.

How to Reduce Pain After a Vaccination?

If your arm is sore after a shot, here are some things you can try to feel better:

• Even though it might hurt, moving your arm can help reduce stiffness and pain. Gentle arm movements and stretches can improve blood flow and disperse the vaccine, aiding in quicker recovery and reducing discomfort.

• Put a cold, damp cloth or an ice pack wrapped in a towel on your arm for about 10-15 minutes at a time. This can help numb the area, reduce swelling, and alleviate pain. Repeat this as needed throughout the day to manage discomfort.

• Over-the-counter pain relievers like ibuprofen or acetaminophen can help manage pain and reduce inflammation. Always check with an adult or healthcare provider before taking any medicine to ensure it is appropriate for you and follow the recommended dosage instructions.

If your arm really hurts, take it easy for a day or two. Avoid strenuous activities and heavy lifting to prevent further soreness and strain, allowing your arm to recover more quickly.

How to Prevent Arm Soreness after a Vaccine?

While you can’t completely prevent arm soreness, there are several strategies to minimize discomfort:

• Try to keep your arm loose and relaxed when getting the shot. Tensing up can make the injection more painful.
• After the shot, gently move your arm around. This can help spread the vaccine more evenly and reduce pain and stiffness later.
• Drink plenty of water before and after your shot. Staying hydrated can help your body manage the vaccine more effectively and aid circulation.
• During the injection, try to distract yourself by talking to someone, listening to music, or focusing on your breathing. Distraction can help reduce the perception of pain.
• Choose the non-dominant arm. This means if you’re right-handed, get the shot in your left arm (or vice versa). This way, your dominant arm won’t be sore, making it easier to go about your daily activities.
• In most cases, after the shot, applying a cold compress to the injection site can help reduce swelling and numb the area, alleviating pain.
• If needed, consider taking over-the-counter pain relief, such as acetaminophen, to help manage pain and reduce inflammation.
• Opt for loose-fitting sleeves or sleeveless tops when going for your shot. This makes it easier for the healthcare provider to administer the vaccine and can help you avoid additional irritation and possible discomfort.
• Try to avoid strenuous activities or lifting heavy objects with the arm that received the shot for at least a day. This is important as it can help prevent further soreness and strain.

If you experience severe or prolonged pain, consult with your healthcare provider for proper care and support. You may also be eligible for a vaccine injury claim.

Discuss Possible Compensation with a Vaccine Injury Attorney

While vaccines are generally safe and their benefits far outweigh the risks, rare serious reactions can occur. The National Vaccine Injury Compensation Program (VICP) offers support for those affected.

If you or someone you know experiences a serious reaction to a vaccine, consult a doctor immediately to determine if it is vaccine-related and get appropriate treatment. Keep detailed records of the vaccination and medical visits, and report the reaction to the Vaccine Adverse Event Reporting System (VAERS).

Consult our Jeffrey S. Pop & Associates vaccine injury attorneys by calling (310) 273-5462) or contacting us online to assess eligibility for compensation and guide you through the VICP process.

The VICP is a “no-fault” system, meaning compensation doesn’t require proving wrongdoing, and attorneys are paid only if you win.
