What Shockwave Therapy Feels Like — And How You Know It Is Working
When patients come in for their first shockwave therapy session, there is usually a version of the same question: what is this actually going to feel like?
It is a fair thing to want to know before you commit to something. The name does not help; shockwave sounds considerably more alarming than the treatment itself.
Here is the straightforward answer, based on what patients consistently describe in clinic, plus what to look for as treatment progresses.
In the session
Shockwave therapy, or extracorporeal shockwave therapy (ESWT), delivers focused acoustic energy to damaged tissue through the skin. There is no injection, no incision, no anaesthetic.
You will typically be seated or lying down comfortably, with the treatment area exposed.
Get comfortable
You will usually be seated or lying down with the affected area positioned so your clinician can access it easily.
Coupling gel
A coupling gel is applied to the skin, similar to what you would find during a physiotherapy ultrasound session.
Focused pulses
The treatment head is held against the affected area and delivers a series of short, focused pulses into the tissue.
The sensation is distinctive but not straightforward to describe in advance.
Most patients characterise it as a rapid tapping or pulsing against the skin, with a deeper, duller pressure beneath the skin.
The intensity can vary: when the head passes directly over the most damaged or inflamed part of the tendon, there is often a sharper response; some people describe it as a brief catch or sting. When the treatment head moves to surrounding tissue, it typically becomes more comfortable.
What does it feel like on a 1–10 scale?
On a scale of one to ten, the honest average is somewhere between four and six during the most active part of treatment. Uncomfortable, yes. Painful in the way that a sharp injury is painful, no.
Most patients find it easy to tolerate. Each pulse is brief, and the session lasts between fifteen and twenty minutes.
Immediately after the session
Once the session ends, the treated area will often feel warmer than usual. There may be some redness at the skin surface — a normal inflammatory response to the acoustic energy.
Some patients notice mild bruising at or around the treatment site, which typically resolves within a day or two.
✓ Warmth
The treatment area may feel warmer than normal immediately after the session.
✓ Mild redness
Temporary redness around the treatment site can occur after shockwave.
✓ Temporary soreness
Some soreness in the hours following treatment is common and expected.
✓ Mild bruising
Some patients notice mild bruising around the treated area, which typically settles within a day or two.
Temporary soreness in the hours following treatment is common and expected. This is not a sign that anything has gone wrong; it is the tissue responding to treatment.
We recommend avoiding anti-inflammatory medication in the days immediately after a session because the inflammatory response that shockwave triggers is part of how it promotes healing. Suppressing it pharmacologically works against the treatment.
No downtime: normal daily activity can resume immediately. There is no recovery period and no need to take time off work for a shockwave session.
How you know it is working
This is where patience becomes important, because shockwave therapy does not work like a painkiller.
The mechanism is biological — it stimulates the body's own tissue repair process, encouraging collagen production, new blood vessel formation and the breakdown of calcification in the tendon.
This takes time to produce visible results.
Why improvement can take time
Treatment encourages tissue-repair processes rather than simply masking symptoms.
Shockwave stimulates biological responses associated with tissue healing and local circulation.
Improvement develops progressively as the affected tissue responds over time.
What the timeline typically looks like
Early response
Some patients notice a brief window of reduced pain in the day or two following each session, followed by a return to baseline. This is normal at the early stage and does not mean treatment is not working.
More sustained improvement
Most patients begin to notice more sustained improvement: pain during activity starts to decrease, morning stiffness settles faster, and they can load the tendon with less discomfort. This is the stage where the structural tissue changes are accumulating.
The effect continues to develop
Six to eight weeks after completing the course, the full effect of treatment continues to develop. This is when most patients notice the clearest difference relative to where they started.
Not noticing any change after two sessions? It is worth discussing this with your clinician. Occasionally, the presentation requires a different approach or a closer look at whether the diagnosis accurately identifies the tissue that needs treatment.
How many sessions?
A typical course at We Fix Feet
Most protocols at We Fix Feet involve three to five sessions, spaced a week to two weeks apart. The number depends on the specific condition, how long it has been present, and how the tissue responds to initial sessions.
This is all outlined in detail at your assessment.
