Most people can feel the Nexplanon implant as a small, firm rod under the skin of their upper arm shortly after insertion.
Understanding the Physical Sensation of Nexplanon
Nexplanon is a small, flexible rod about the size of a matchstick that is inserted just beneath the skin of the upper arm. Because it sits close to the surface, many users can physically feel it with their fingertips. The implant is designed to release a steady dose of etonogestrel, a hormone that prevents pregnancy for up to three years.
Feeling Nexplanon after insertion is normal and expected. It usually feels like a firm, smooth bump under the skin. The sensation varies depending on individual factors such as body fat, muscle mass, and skin thickness. Some women describe it as feeling like a small piece of plastic or a tiny tube embedded under their skin. For others with more subcutaneous fat or muscle, it might be less noticeable or even hard to detect by touch.
The key point is that Nexplanon is not supposed to be painful or cause discomfort when touched once properly healed. If you experience sharp pain, redness, swelling, or any signs of infection around the implant site, it’s crucial to seek medical advice immediately.
The Insertion Process and Its Impact on Sensation
The way Nexplanon is inserted plays a significant role in how noticeable it feels afterward. The procedure is performed by a trained healthcare provider using local anesthesia. A small incision is made in the inner side of the upper arm, and the implant is slid just under the skin into place.
Immediately after insertion, some tenderness and mild soreness are common due to tissue trauma from the needle and placement process. This soreness typically subsides within a few days to weeks as your body adjusts.
During this healing period, you might feel more aware of the implant—like a foreign object resting beneath your skin—especially if you press on it or move your arm in certain ways.
Over time, most users report that they become less conscious of its presence as their body adapts and any initial discomfort fades away.
Why Some People Feel It More Than Others
Several factors influence how distinctly you can feel Nexplanon in your arm:
- Body Composition: Individuals with thinner arms or less fat tend to feel the implant more easily.
- Placement Depth: Proper insertion just beneath the skin ensures it’s palpable but not deep enough to cause pain.
- Healing Response: Swelling or scar tissue formation can temporarily change how noticeable it feels.
- Nerve Sensitivity: Some people have heightened sensitivity around the insertion site.
If you have concerns about how prominent or painful your implant feels, your healthcare provider can assess its position using palpation or ultrasound imaging.
Sensory Changes Over Time: What to Expect
Right after insertion, sensory changes are common but usually short-lived. You might notice:
- A slight tingling sensation near the site
- Mild numbness due to local anesthesia wearing off
- A feeling of tightness when moving your arm
These sensations typically improve within days or weeks. Long-term numbness or persistent pain is rare but should be evaluated promptly.
It’s also normal for users to occasionally check for their implant by touch throughout its lifespan. Being able to feel it reassures many women that it’s still in place and functioning properly.
The Role of Implant Location in Feeling Nexplanon
Nexplanon should be inserted subdermally — directly beneath the top layer of skin but above muscle tissue. This shallow placement makes it easier to feel while minimizing discomfort.
If inserted too deeply into muscle tissue, it may become harder to detect by touch but could increase pain during movement or palpation.
Conversely, if placed too superficially (too close to the surface), there’s an increased risk of irritation or even migration from its original spot.
Healthcare professionals are trained extensively on proper technique to balance these considerations for optimal comfort and effectiveness.
The Safety Aspect: Feeling Versus Complications
Feeling Nexplanon under your skin isn’t cause for alarm; it’s part of normal use. However, certain symptoms related to sensation should never be ignored:
- Persistent severe pain: Could indicate nerve involvement or improper placement.
- Lump enlargement: May signal infection or granuloma formation.
- Numbness spreading beyond insertion site: Might suggest nerve compression.
- Migrating implant: If you notice that what you feel has shifted significantly from its original spot.
If any of these occur alongside changes in how you feel your implant, consult your healthcare provider immediately for examination and possible ultrasound imaging.
Nexplanon Removal and Sensation Changes
When it’s time for removal—usually after three years—the provider makes a small incision near where it was inserted and gently extracts the rod.
Some users report increased tenderness during removal compared to insertion due to scar tissue formation around the device over time.
After removal, sensations caused by having an object under your skin disappear quickly. There may be temporary soreness at the removal site but no lasting changes in sensation unless complications arise.
The Hormonal Impact Does Not Affect Physical Feeling
Nexplanon’s primary function is hormonal; it releases etonogestrel steadily into your bloodstream without causing physical sensations related directly to hormones at its location.
While hormonal side effects such as mood changes, spotting irregularities, or breast tenderness may occur systemically, they don’t influence whether you can physically feel Nexplanon in your arm.
Therefore, any sensation you experience at the site relates solely to its physical presence rather than hormonal activity.
Nexplanon Compared To Other Contraceptive Implants: Sensation Differences
Not all contraceptive implants are identical when it comes to size and placement method. Here’s how Nexplanon stacks up against other options:
| Name | Size (mm) | Sensation Under Skin |
|---|---|---|
| Nexplanon | 40 x 2 mm | Easily felt; firm rod just beneath skin |
| Implanon (predecessor) | 40 x 2 mm | Easily felt; similar profile but less radiopaque than Nexplanon |
| Sino-implant II (China) | Larger & thicker rod (varies) | Slightly more prominent due to size; firmer sensation reported by users |
| Etonogestrel Implant Variants (Other brands) | Slight size variations around 40 mm length | Sensation comparable; depends on placement technique |
Nexplanon’s design improvements over previous models include better visibility on X-rays and MRI scans due to added barium sulfate content—helpful if locating becomes necessary—but this does not affect tactile sensation directly.
Troubleshooting When You Can’t Feel Your Implant Well
Sometimes users worry because they cannot easily find their Nexplanon by touch after insertion:
- If you cannot locate it within two weeks post-insertion despite trying gently along expected area (inner upper arm), consult your doctor.
- An ultrasound scan can confirm proper positioning beneath skin layers.
- If misplaced too deeply or migrated slightly from original site (rare), removal may require imaging guidance.
- A missing implant could indicate expulsion—a rare event where device falls out unnoticed—and alternative contraception should be used until replacement.
- Your healthcare provider will rule out these issues through physical exam and diagnostic tools before reassuring you about safety.
