About nerve entrapment
Nerves travel through narrow tunnels formed by bone, ligament, muscle, and fascia. When a tunnel becomes tight, or scar tissue binds a nerve in place, the nerve can be compressed or unable to glide normally as you move. This is called nerve entrapment, or compressive neuropathy.
Common examples include the median nerve at the wrist (carpal tunnel syndrome), the ulnar nerve at the elbow, and smaller nerves around the hip, knee, and ankle. Symptoms usually follow the path of the affected nerve, which is why a careful map of where you feel them helps guide diagnosis.
Common symptoms
- Numbness or tingling in a specific patch of skin
- Burning or shooting pain along the course of a nerve
- Symptoms that worsen with certain positions, such as a bent elbow or wrist
- Weakness or clumsiness in the muscles the nerve supplies
- Night symptoms that wake you up
Common causes and risk factors
- Repetitive motion or sustained positions that press on a nerve
- Swelling, cysts, or thickened tissue within a tight tunnel
- Scar tissue after injury or surgery
- Diabetes, thyroid disease, or pregnancy, which can make nerves more sensitive to pressure
How we diagnose it
Our physicians begin with a hands-on exam that tests sensation, strength, and the spots where tapping or pressure reproduces symptoms. Ultrasound at the exam table lets us see the nerve directly, check for swelling or flattening, and look for a cyst or scar that may be pressing on it. When the picture is unclear or weakness is present, Dr. Chen may perform an EMG and nerve conduction study to confirm which nerve is involved and how much it is affected.
How Propel treats nerve entrapment
Conservative care comes first. That may include adjusting the positions and tasks that aggravate the nerve, a night splint when appropriate, nerve gliding exercises, and strength work for the surrounding muscles so the area handles load better. We want you to keep training and working, so the plan focuses on how to stay active rather than a long list of things to avoid.
If symptoms persist, nerve hydrodissection may help. Under live ultrasound, the physician places fluid around the nerve to separate it from the tissue that is binding it, and the physician performs the procedure personally in the office. When there is significant or worsening weakness, or the nerve does not improve, we discuss other procedures or help coordinate a surgical referral.
What to expect at your visit
- 1.
We listen first
Your visit opens with a real conversation: how the problem started, what you have already tried, and the activity you want back.
- 2.
Exam and in-office ultrasound
A hands-on exam, then ultrasound at the exam table, often while you move, so your physician can see the tendon, joint, or nerve involved.
- 3.
A clear diagnosis and plan
You leave knowing what is wrong and what your options are, from strength-based rehab to procedures, and why we recommend each one.
- 4.
Treatment and follow-through
Most procedures happen here in the office. We coordinate with your physical therapist and check progress against the goals you set.
Questions about nerve entrapment
- How is nerve hydrodissection different from a steroid injection?
- Hydrodissection uses a volume of fluid, placed under ultrasound, to mechanically free a nerve from the tissue around it. A small amount of medication may be included, but the main goal is to give the nerve room to move. Our physicians explain which option fits your situation.
- Does a trapped nerve usually need surgery?
- Many people improve with conservative care and office-based procedures. Surgery is considered when there is ongoing muscle weakness, loss of muscle bulk, or symptoms that do not respond to other treatment, and we help coordinate that referral when it is the right step.
- Can a nerve be trapped in more than one place?
- Yes. A nerve can be irritated at two points along its path, such as the neck and the wrist, which can make symptoms harder to sort out. Nerve testing and ultrasound help identify every site that is contributing.
