Perineural Injection Therapy (PIT) For Pain Brooklyn NYC

Perineural injection therapy, often referred to as PIT, is a treatment option some patients explore when chronic nerve-related pain hasn’t responded well to more conventional approaches.

What Perineural Injection Therapy Involves

PIT involves injecting a dilute dextrose solution just under the skin, near nerves in the area where pain is felt, rather than into the joint or muscle itself. The theory behind the treatment is that chronically irritated peripheral nerves can become inflamed and overly sensitive, a state sometimes called neurogenic inflammation, and that the injections may help calm that irritation. The underlying nerve science is examined in PIT therapy and the peripheral nerve matrix.

It’s worth being direct that PIT is a newer, less established treatment compared to options like physical therapy or steroid injections, and the research base is still developing. Some patients and practitioners report meaningful relief, particularly for chronic, localized nerve-type pain, but results are not consistent or guaranteed, and larger, high-quality studies are still limited. That trade-off is discussed in shockwave as an alternative to surgery and steroids.

Conditions Sometimes Treated With PIT

Patients typically ask about PIT for chronic regional pain that hasn’t improved with other treatments, including certain cases of nerve-related back, neck, or joint pain. Because the evidence is still emerging, PIT is usually considered after more established treatments have been tried, not as a first-line option.

What a Session Feels Like

The injections are shallow, just under the skin, and most patients describe brief stinging at each injection point rather than significant pain. Sessions are generally well tolerated, and side effects such as temporary redness or soreness at the injection sites are uncommon and short-lived. A treatment plan usually involves multiple sessions rather than a single visit.

Is PIT Right for You?

Because PIT is still an evolving treatment, a thorough evaluation is important before starting, so your provider can talk through what’s realistic for your specific condition. Individual results vary, and PIT is not guaranteed to relieve pain.

If you’re in Brooklyn and want to discuss whether perineural injection therapy could be part of your treatment plan, a pain management provider can walk you through the options, including what the evidence does and doesn’t show.

Frequently asked questions

What kind of pain is PIT least likely to help?
Pain driven by clear structural damage. Where the main problem is an advanced arthritic joint, a significant tear, a compressed nerve root or an inflammatory disease, a superficial dextrose injection is not addressing the cause. It is aimed at irritation of small nerves near the surface, so the evaluation is largely about deciding whether that picture fits.

Can several sites along a nerve path be treated in one PIT session?
Often yes, since each site takes only a moment and the injections stay superficial. The practical limits are the total volume that is reasonable in one sitting, how much brief stinging a person wants to tolerate, and whether treating a long stretch at once makes it harder to judge what responded. A provider decides that case by case.

How is PIT different from a nerve block?
A nerve block uses anesthetic, sometimes with steroid, to interrupt signals from a specific nerve, often placed under image guidance. Perineural injection therapy instead puts dilute dextrose into the tissue just under the skin near the nerve, aiming to settle irritation rather than numb the area. Blocks are also used diagnostically, which is not the purpose of PIT.

Is a small bump or stinging at the injection sites normal after PIT?
Yes. A raised bump where the fluid sits under the skin is expected and settles within hours, and brief stinging during the injection is the sensation most people describe. Redness that spreads, increasing pain over the following days, or fever is a different matter and should be reported rather than waited out.
