Nexplanon is designed to stay firmly in place under the skin and does not move significantly within the arm.
Understanding Nexplanon’s Placement and Stability
Nexplanon is a small, flexible rod about the size of a matchstick, inserted just beneath the skin of the upper arm. Its primary function is to release hormones steadily over time to prevent pregnancy. The question “Can Nexplanon Move In Your Arm?” arises because users sometimes feel discomfort or notice changes around the insertion site.
The implant is placed in the subdermal tissue, which means it sits beneath the skin but above the muscle. This placement ensures it remains relatively stable. The body’s tissue naturally holds the rod in place, preventing significant movement. The implant’s design and insertion technique minimize any chance of it migrating extensively within the arm.
Despite this, slight shifts can happen due to normal arm movements or physical activity, but these are minimal and generally unnoticeable. The implant doesn’t travel through blood vessels or muscles; instead, it stays localized in its initial position.
How Nexplanon Is Inserted
The insertion process plays a critical role in ensuring that Nexplanon stays put. A trained healthcare provider uses a special applicator to place the implant beneath the skin in a precise spot on the inner side of the upper arm.
During insertion:
- The area is numbed with local anesthesia.
- The applicator inserts Nexplanon just under the skin.
- The provider checks for proper placement by feeling for the rod.
Because of this careful procedure, most implants remain firmly lodged without moving around. Once inserted, scar tissue begins to form around it, further securing its position over time.
Why People Think Nexplanon Might Move
It’s common for users to worry about movement when they feel sensations near or around their implant. Here are some reasons why these concerns arise:
- Palpation Sensitivity: Sometimes, touching or pressing near the implant can make it feel like it’s shifting.
- Swelling or Bruising: After insertion, minor swelling or bruising can create an illusion of movement as tissues settle.
- Arm Activity: Vigorous exercise or muscle contractions might cause slight shifts in surrounding tissue, not necessarily moving the implant itself.
- Nerve Sensations: Some users report tingling or discomfort that feels like movement but is actually nerve irritation near the site.
While these sensations can be unsettling, they rarely indicate actual migration of Nexplanon within your arm.
The Difference Between Movement and Migration
It’s important to distinguish between minor movement and true migration:
- Movement: Small shifts caused by normal muscle activity or tissue elasticity; typically harmless and limited.
- Migration: Significant displacement from the original site; extremely rare with Nexplanon due to its design and placement technique.
Cases of implants migrating far from their insertion point are exceedingly uncommon and usually involve improper insertion or trauma.
The Science Behind Implant Stability
Nexplanon’s material composition contributes heavily to its stability. Made from a soft polymer that is biocompatible with human tissue, it integrates comfortably without causing excessive irritation.
Once implanted:
- The body forms a thin fibrous capsule around it.
- This capsule acts like a natural anchor holding it steady.
- The polymer’s flexibility allows for slight bending without displacement.
This biological response ensures that even with daily movements—lifting objects, bending arms, or exercising—the implant remains where it was placed.
What Does Research Say About Implant Movement?
Clinical studies involving thousands of women using Nexplanon report very low rates of migration. When migration does occur, it tends to be minimal—measured in millimeters rather than centimeters—and rarely causes complications.
A review published in medical journals highlights that proper insertion technique combined with post-insertion care significantly reduces any chance of displacement. Healthcare providers are trained specifically on how to avoid deep placement (which could increase risk) and ensure superficial subdermal positioning.
Signs That Might Indicate an Issue With Your Implant
Though Nexplanon rarely moves significantly inside your arm, some symptoms warrant medical attention:
- Implant Not Palpable: If you can’t feel your implant at all after insertion or suddenly lose touch with it later on.
- Pain or Swelling: Persistent pain beyond typical soreness could signal infection or improper placement.
- Numbness or Tingling: Continuous nerve-related symptoms may require evaluation.
- Visible Changes: Redness, lumps, or unusual skin changes at insertion site.
If any of these occur, consult your healthcare provider immediately for an examination and possible ultrasound imaging to locate your implant.
The Role of Ultrasound and X-rays
If there’s concern about Nexplanon’s position:
- Ultrasound: Often used first because it’s non-invasive and effective at locating implants beneath skin layers.
- X-rays: Useful if ultrasound is inconclusive; Nexplanon contains barium sulfate which makes it visible on X-rays.
These imaging techniques confirm whether your implant has shifted significantly and help guide removal if necessary.
Caring for Your Arm Post-Insertion to Avoid Movement
Proper care after receiving Nexplanon helps prevent complications that might mimic movement:
- Avoid heavy lifting with your arm for at least 24-48 hours after insertion.
- Keeps the area clean and dry to reduce infection risk.
- Avoid pressing firmly on the implant site during healing period.
- If bruising occurs, apply cold compresses gently but do not massage aggressively near insertion point.
Following these guidelines supports healing tissues anchoring your implant securely.
Nexplanon Removal Considerations Related to Movement
When it’s time for removal (usually after three years), providers rely on palpation first. If they can’t feel it easily due to swelling or other factors, imaging helps locate it precisely before extraction.
In rare cases where implants have migrated slightly deeper into tissue planes:
- Surgical removal may be necessary under local anesthesia.
- This procedure remains safe and effective when performed by experienced clinicians.
No matter what stage you’re at with your implant journey—whether considering removal or concerned about movement—professional guidance ensures safety.
