Sciatic nerve
Used for pain that travels from the lower back or buttock down the leg and may help relieve irritation contributing to sciatica.
Nerve Hydrodissection
A minimally invasive ultrasound-guided procedure that uses saline and dextrose around a nerve to reduce irritation, pressure, and scar-related restriction.
Overview
A minimally invasive ultrasound-guided procedure that places fluid around an irritated nerve to ease pressure, release scar tissue, and reduce pain.
Common treatment areas
Median nerve
Used for carpal tunnel symptoms such as numbness, tingling, or weakness in the hand and fingers, including patients hoping to avoid or delay surgery.
Ulnar nerve
Used for numbness or tingling in the ring and little fingers, pain along the inner forearm or hand, and symptoms related to cubital tunnel syndrome.
Abdominal wall nerves
Used for localized abdominal wall pain, including pain after surgery, injury, or strain.
Ultrasound-guided nerve approach
Ultrasound guidance helps separate irritated nerves from surrounding tissue.
What patients may notice afterward
The experience after nerve hydrodissection varies from patient to patient. Some notice improvement shortly after the procedure, while others find that relief builds gradually over several days to weeks as inflammation decreases and the nerve settles.
- Mild soreness or bruising at the injection site
- A feeling of fullness where the fluid was injected
- Temporary numbness or tingling
- Some patients feel better right away, while others improve gradually over several days to weeks
Aftercare and recovery
- Apply an ice pack for 10 to 15 minutes at a time
- Take acetaminophen (Tylenol) if needed
- Avoid heavy activity for 24 to 48 hours
When to contact the clinic
- Increasing redness, swelling, or warmth
- Fever or chills
- Severe or worsening pain
Why this procedure is considered
Nerve hydrodissection is chosen when a nerve appears to be restricted, irritated, or under pressure from surrounding tissue, and when a minimally invasive approach is appropriate.
The procedure does not involve surgery. Ultrasound guidance allows the physician to visualize the nerve in real time and place the fluid precisely. Recovery is generally brief, and most patients resume light activity within one to two days.
Next Step
Discuss whether nerve hydrodissection is appropriate.
The clinic can review your symptoms, prior treatment, imaging, and whether this procedure fits into your care plan.
If you have a question after a recent procedure, call the clinic directly rather than waiting for an online response.
