Experiencing discomfort around an arm implant, even years after its initial placement, can be a source of concern. While these implants are generally well-tolerated and effective for their intended purpose, individuals sometimes report pain or unusual sensations over time. Various factors can contribute to such discomfort, ranging from the body’s natural response to a foreign object to external influences.
Potential Causes of Pain Years Later
The body’s reaction to an implanted device can cause localized pain years later. Scar tissue often forms around the implant as part of the healing process. Sometimes, this tissue becomes dense or forms adhesions that press on surrounding structures.
Pressure from scar tissue can irritate or entrap nearby nerves. This nerve irritation may cause localized pain, burning, tingling, or numbness extending into the hand. The implant’s proximity to superficial nerves, like the medial cutaneous nerve of the forearm, can lead to persistent symptoms.
In rare instances, the implant may subtly migrate from its original site. Minor shifts can occur, especially if it moves into an area with more nerve endings or muscle tissue. Even slight movement can cause new or increased pain as it interacts differently with the surrounding anatomy.
Chronic low-grade inflammation or a delayed infection can also cause pain, though less common after two years. While acute infections usually appear soon after insertion, a persistent inflammatory response or slow-developing bacterial presence might cause ongoing discomfort. This inflammation may not show overt signs like pus or significant redness.
A delayed localized allergic reaction to implant materials is another possible cause, though rare. Implants like Nexplanon contain a progestin hormone encased in ethylene vinyl acetate copolymer. While generally inert, a hypersensitivity response could develop over time, leading to localized inflammation and pain.
A direct impact or injury to the arm can cause localized pain, regardless of the implant. Even a minor bump or pressure can exacerbate sensitivities or create new discomfort. The implant may become more noticeable if surrounding tissue is bruised or inflamed from trauma.
When to Consult a Healthcare Provider
Consult a healthcare provider if arm implant pain persists or worsens. Professional evaluation is needed if pain doesn’t resolve with self-care like rest or over-the-counter relievers. Seek help especially if discomfort interferes with daily activities or sleep.
Any changes in arm sensation, such as new numbness, tingling, or hand weakness, require a healthcare provider visit. These symptoms indicate potential nerve involvement and need prompt assessment to rule out compression or irritation.
Even subtle signs of infection, though rare after two years, need medical attention. These include persistent redness, swelling, warmth, or discharge around the implant site. While fever is less common with delayed issues, its presence with localized symptoms indicates immediate consultation.
Consult a healthcare provider for visible changes at the implant site, such as new lumps, bumps, or skin discoloration. Also seek evaluation if you can no longer easily feel the implant or if it feels significantly moved from its original position.
What to Expect During a Medical Evaluation
A medical evaluation for arm implant pain typically begins with a thorough medical history. The doctor will ask detailed questions about your pain’s nature, onset, severity, and any associated symptoms. They will also inquire about recent injuries or health changes.
After the discussion, a physical examination of the implant site and surrounding arm will be performed. The provider will palpate the area to assess the implant’s position, check for tenderness, swelling, or tissue abnormalities. They will also evaluate your arm’s range of motion and nerve function.
Imaging studies may be recommended to understand the implant’s position and surrounding structures. Ultrasound is often the first-line modality, visualizing the implant and identifying issues like scar tissue, nerve impingement, or fluid collections. An X-ray might confirm the implant’s presence, but it doesn’t provide detailed soft tissue information.
After reviewing examination and imaging findings, your healthcare provider will discuss the likely cause of your pain. Treatment options vary by diagnosis. Simple pain management with over-the-counter medications and observation may be suggested for minor causes.
If nerve irritation or inflammation is identified, specific treatments like anti-inflammatory medications or local injections might be considered. For persistent, severe pain, or issues like implant migration, removal may be recommended. If continued contraception is desired, your provider can discuss replacement or alternative methods.
