Do Blood Tests Hurt More Than Shots?


If you are wondering, “Do blood tests hurt more than shots?”, it depends on several factors like the type of needle used, the skill of the person doing the blood test or shot, and the person receiving the poke or injection.

In fact, if you ask different people which one hurt the most, you will get some saying that blood tests hurt more and others saying that shots hurt more. It all depends on who you are talking to. There are times when a blood test doesn’t hurt and times when it does. And, there are times when a shot does hurt and doesn’t!

While the answer can vary depending on several factors such as the kind of shot, type of needle used, state of mind, and individual pain tolerance, let’s dive into the key differences between blood tests and shots and what you can expect in terms of pain and discomfort.


Understanding the Basics: Blood Tests vs. Shots

Before we get into the specifics of pain, it helps to understand what’s happening during each procedure:

  • Blood Tests: In a blood test, a nurse, doctor, or phlebotomist uses a needle to draw blood, usually from a vein in your arm. The goal is to collect a sample for testing, which can provide important information about your health.
  • Shots: A shot (or injection) involves using a needle to deliver medication, a vaccine, or another substance into your body. This can be done in a muscle (intramuscular), just under the skin (subcutaneous), or in a vein (intravenous).

Both procedures involve needles, but their purpose and how they are performed differ slightly, which can impact how they feel.

How Do Blood Tests Feel?

The sensation of a blood test usually starts with a small pinch as the needle enters your skin and vein. You might feel slight pressure as the healthcare professional collects the blood, but this part is typically painless.

Factors that can influence the experience:

  • The Skill of the Phlebotomist: A skilled phlebotomist can make the process quick and nearly pain-free. Someone who is new or has less experience can take longer and possibly bring about more discomfort.
  • Vein Accessibility: If you have small or hard-to-find veins, it might take a bit more effort to insert the needle, which could cause some minor discomfort.
  • Your State of Mind: Anxiety or nervousness can make the experience feel more intense than it really is.

For most people, the discomfort of a blood test is minimal and over within seconds.

How Do Shots Feel?

Shots can feel a bit different because they involve injecting something into your body rather than drawing something out. The sensation depends on several factors:

  • The Type of Shot:
    • Vaccines or medications that are thicker in consistency can cause more noticeable pressure or soreness as they are injected.
    • Subcutaneous Injections, given just under the skin, are usually less painful than intramuscular shots, which go deeper into the muscle.
  • The Injection Site: Shots given in larger muscles (like the upper arm or thigh) might feel sorer afterward than those given in smaller areas.
  • Aftereffects: Some shots, like vaccines, can cause temporary muscle soreness or a mild burning sensation at the injection site.

While the initial needle prick may feel similar to a blood test, the sensation of the medication entering your body can add a slight difference in discomfort.

Comparing the Pain: Blood Tests vs. Shots

As already mentioned above, the answer varies depending on several factors. So, which one hurts more? Here’s a comparison based on common experiences:

  • Duration: Blood tests usually take a few seconds longer than a shot because the needle stays in place to collect the sample. However, the discomfort doesn’t necessarily increase with time. The pain felt is usually when the needle enters the skin and vein. Once the needle is in the vein it usually doesn’t hurt anymore, unless the patient moves their arm or the needle moves.
  • Sensation: Shots may cause a slight stinging or burning sensation as the medication is injected, whereas blood tests might involve a sense of pressure but less burning.
  • Size of Needle: Needles used to draw blood are usually bigger than needles used to perform shots. Maybe it can be said that a smaller needle may cause less pain than a bigger needle. However, the sites used for blood tests and shots are different and the depth the needles go varies. So, a smaller needle may not necessarily hurt less.
  • Aftereffects: Shots can leave your arm or leg feeling sore for a day or two, especially after vaccines. Blood tests rarely cause lingering discomfort unless there’s bruising from the needle insertion.

In general, neither procedure is extremely painful, and both are designed to minimize discomfort as much as possible.

Tips to Minimize Discomfort

If you have to do a blood test or take a shot and want some tips on things to do to lessen the pain or discomfort, here are some to make the procedure easier:

  1. Try to Stay Relaxed: Take deep breaths to calm your nerves and reduce muscle tension. Relaxed muscles make the procedure easier and less painful.
  2. Communicate: Let the nurse or phlebotomist know if you’re nervous or have a low pain tolerance. They can adjust their approach to make you more comfortable.
  3. Distract Yourself: Focus on something else during the procedure—count backward, listen to music, or chat with the technician.
  4. If you are very anxious or scared you can ask the person taking your blood to use a numbing cream to apply to the area so that you don’t feel the needle going in.

Final Thoughts

So, do blood tests hurt more than shots? As you would have found out from reading this article, there is not a definitive answer. The answer really is subjective to a large degree. The truth is, there are times when blood tests hurt more than shots and there are also times when shots hurt more than blood tests. The pain felt really depends on factors such as the type of needle, the person’s state of mind, the skill of the nurse or phlebotomist, how deep the needle goes, and the size of it.

If you talk with a hundred people you will get varying answers. Some will say blood tests don’t hurt. Others will say blood tests hurt. And the same will be said about shots. Their answers really are based on their personal experience. However, there is a slight pain that may be felt when a needle enters the skin and into the surrounding tissues, whether it’s for a blood test or shot. The one that hurts the most will depend on some of the factors mentioned above.
