Pinched nerves have a particular kind of misery to them: burning, tingling, numbness, or shooting pain that doesn’t always match up neatly with an injury you can point to. If you’ve been told a nerve is “entrapped” or “compressed” and the only options presented were medication or surgery, there’s a middle path worth understanding — nerve hydrodissection.
Understanding Nerve Entrapment
Nerves travel through narrow tunnels of muscle, tendon, and connective tissue throughout the body. When surrounding tissue becomes inflamed, scarred, or thickened — from repetitive motion, injury, or postural strain — it can compress the nerve as it passes through, a condition often called nerve entrapment or a pinched nerve. Common sites include the wrist, elbow, shoulder, and lower back, and the resulting pain can radiate well beyond the site of compression.
How Nerve Hydrodissection Works
Nerve hydrodissection is a minimally invasive, image-guided procedure in which a physician injects a small volume of fluid — typically a saline or anesthetic solution — around a compressed or irritated nerve. Using ultrasound guidance, the fluid is placed precisely along the nerve’s path to gently separate it from the surrounding tissue that’s binding or compressing it.
The goal is mechanical as much as medicinal: by creating space between the nerve and the tissue trapping it, hydrodissection can reduce friction, ease inflammation, and interrupt the cycle of irritation that keeps the nerve sending pain signals. Because it’s guided by real-time imaging, the procedure can target the exact location where compression is occurring, rather than treating the area in general.

What Hydrodissection Can Help With
- Carpal tunnel syndrome and other wrist nerve entrapments
- Cubital tunnel syndrome (ulnar nerve compression at the elbow)
- Peripheral nerve pain following injury or surgery
- Sciatic nerve irritation contributing to leg pain
- Chronic localized nerve pain that hasn’t responded to conservative care
At TeamMD, hydrodissection is one of several tools our specialists use alongside Nerve Blocks to relieve nerve-related pain without surgery, particularly for patients dealing with Radiculopathy or Sciatica.
What to Expect During the Procedure
Nerve hydrodissection is typically performed in-office and takes only a matter of minutes. Using ultrasound imaging, your physician locates the affected nerve and guides a thin needle to the precise area of compression, then slowly injects the fluid to create separation along the nerve’s path. Most patients feel a sensation of pressure or fullness rather than significant pain, and local anesthetic is used to keep the process comfortable.
Because it’s minimally invasive, there’s no surgical incision and typically little to no downtime — many patients resume normal activities the same day, with some soreness at the injection site for a day or two.
How Does It Compare to Surgery?
Surgical nerve decompression involves cutting through tissue to physically release the nerve — an approach that can be effective for severe, long-standing compression but comes with a real recovery period, scarring, and surgical risk. Hydrodissection, by contrast, achieves a similar goal of relieving pressure on the nerve using fluid instead of a scalpel, making it a reasonable first step for many patients before surgery is considered.
It’s often combined with PRP Injections or physical therapy for a more complete recovery plan, depending on the underlying cause of the nerve compression.

Frequently Asked Questions
Is nerve hydrodissection painful?
Most patients describe mild pressure rather than pain. A local anesthetic is used, and the procedure itself is brief.
How many hydrodissection treatments will I need?
This depends on the severity and duration of the nerve compression. Some patients notice improvement after a single session, while others benefit from a short series of treatments spaced several weeks apart.
Is hydrodissection a permanent fix?
Results vary by patient and underlying cause. For some, it provides lasting relief; for others, it’s most effective as part of a broader plan that includes physical therapy and activity or ergonomic changes to prevent the compression from recurring.
