The Most Common Question Before the First Session
"Will it hurt?" is, without doubt, the most frequent question from people who have never had electroacupuncture. The honest answer is: the sensation exists, but it is rarely painful — and it is completely different from what most people imagine. Understanding what to expect transforms pre-session anxiety into curiosity, and the first experience into something much more comfortable.
The perception of "pain" during acupuncture is closely tied to expectation and preparation. Neuroimaging studies show that patients well-informed about the expected sensations activate the threat cortex less and the endorphin system more — which in itself enhances the therapeutic effect of the session.
The Sensation of Deqi: What Is It?
In classical Chinese medicine, "deqi" (得氣 — "arrival of qi") is the characteristic sensation that signals correct needle placement at the acupuncture point. In modern neuroscientific terms, deqi corresponds to activation of deep connective-tissue mechanoreceptors and A-delta nerve fibers around the needle.
Deqi can manifest as pressure, heaviness, distension, tingling, local warmth, or a mild electric current radiating along the path of the nerve. It is not pain — it is a new, intense, and specific sensation that most patients learn to recognize and associate with the therapeutic effect. Research shows that sessions with consistent deqi produce better clinical results than sessions without this sensation.
Step by Step of the Sensations in a Session
Needle insertion
1–2 secondsElectroacupuncture needles are very fine (0.25–0.30 mm in diameter — thinner than a strand of hair). Most patients describe a minimal prick on insertion, comparable to a small pinch. At many points, especially in adipose tissue, there is virtually no sensation.
Arrival of deqi
5–30 secondsAfter insertion, the physician makes small adjustments in needle position until deqi is obtained. The patient feels localized pressure, distension, or tingling — a strange but generally not painful sensation. This is where many patients say 'it is different from what I imagined'.
Start of electrical stimulation
1–3 minutes of adjustmentThe stimulator is turned on at the minimum intensity and increased gradually. The frequency determines the type of sensation: at 2 Hz, the patient perceives slow rhythmic contractions ("pulses"); at 100 Hz, a continuous gentle vibration. The physician adjusts up to the level of comfort — below the pain threshold in all cases.
During the session (20–30 min)
20–30 minutesOnce the parameters stabilize, most patients enter deep relaxation — some fall asleep. The released endorphins produce a gentle sense of well-being. Visible rhythmic muscle contraction is normal and indicates adequate stimulation.
After needle removal
Following hoursMild tenderness at the points may persist for 1–4 hours. A sense of lightness, pleasant fatigue, or deep muscle relaxation is very common. A small bruise occasionally appears at the site — normal and clinically insignificant.
Myth vs. Fact
Electroacupuncture is like getting a painful electric shock
The current used is minimal (0.1–1 mA) and produces only tingling or gentle vibration. It is categorically different from an electric shock — there is no sharp, sudden jolt. Patients frequently fall asleep during the session.
Acupuncture needles are like injection needles — they cause intense pain
Acupuncture needles are 10–15 times thinner than hypodermic needles (0.25 mm vs 0.8–1.2 mm) and have a rounded tip that separates tissue rather than cutting it. The comparison is misguided — they are completely different instruments.
If it hurts, it means the treatment is working better
False and potentially dangerous. Intense pain during electroacupuncture signals incorrect needle positioning or excessive electrical intensity — not greater efficacy. Adequate stimulation should always be comfortable. Report any discomfort to the physician immediately.
What to Communicate to the Physician During the Session
Normal sensations — only mention them if they bother you:
- Tingling or vibration at the stimulation points
- Visible rhythmic muscle contractions
- Sensation of warmth or local heaviness
- Radiation of the sensation along the path of the nerve
- Mild drowsiness or deep relaxation
- Sensation of "gentle electric current" between the points
Frequently Asked Questions
Frequently Asked Questions
At most points, needle insertion feels like light pressure or a brief small prick. The electrical stimulation produces tingling or vibration — comfortable when adjusted correctly. Intense pain is neither expected nor acceptable. If you feel pain, say so immediately so the physician can adjust.
Yes. The physician adjusts the intensity gradually and always within your comfort range. You can request an increase or decrease at any time. The goal is always to be below the pain threshold — in the "stimulating comfort zone".
Neither necessary nor recommended without medical indication. If you regularly take anxiolytics, antidepressants, or other medications, keep them as prescribed and tell the acupuncturist physician — never stop medication on your own before a session. For procedure-related anxiety, verbal preparation, familiarization with the technique, and gradual ramp-up of intensity are usually enough.
Deqi is the sensation of pressure, distension, warmth, or tingling that indicates correct activation of the nerve fibers at the acupuncture point. It matters because it signals that the neural signal is being transmitted to the central nervous system — studies show correlation between the intensity of deqi and the release of endogenous opioids and clinical improvement. It is not pain: it is the "signal" that the point is active.
Generally yes — electrical stimulation produces a more noticeable, continuous sensation than manual manipulation. Most patients still find electroacupuncture more comfortable, precisely because the intensity is objectively controlled and stable, unlike manual manipulation, which can vary. After the first 2–3 sessions, patients adapt completely.
