Vaginismus

An involuntary tightening of the muscles around the vaginal opening that makes penetration painful or impossible. It is a reflex, not a decision, and it responds well to structured treatment.

What happens

At the prospect of penetration, whether by a partner, a tampon, a finger or a speculum, the muscles surrounding the vaginal entrance contract sharply and involuntarily. The person often describes a wall, a burning, or a sensation of hitting something solid. Many also notice the whole body responding: legs closing, breath held, back arching away.

The reflex is protective. It behaves exactly like the flinch that follows a hot surface, and it is no more under conscious control. Being told to relax is useless, and being told that it is all in the mind is both inaccurate and counterproductive.

Primary and secondary

Primary vaginismus has been present from the first attempt at penetration. Tampons may never have been possible, and cervical screening may never have been completed.

Secondary vaginismus develops after a period during which penetration was comfortable. There is usually an identifiable trigger: an episode of thrush, a course of painful sex from dryness, a birth injury, surgery, a skin condition, a traumatic examination, or a frightening experience.

Both respond to the same treatment. Secondary vaginismus additionally requires whatever caused the pain in the first place to be treated, because muscle work alone will not hold while the original problem is still there.

Contributing factors

There is rarely a single cause. Factors that appear often include fear of pain, which is entirely rational once pain has happened; anxiety in general; beliefs absorbed early about sex being dangerous, shameful or damaging; inaccurate ideas about anatomy, particularly the belief that the opening is too small; previous painful examinations; and a history of sexual trauma, which is present in some cases and absent in many others.

The muscular pattern is real regardless of the origin. Examination typically finds raised resting tone throughout the pelvic floor, which is why the condition sits alongside an overactive pelvic floor rather than being separate from it.

Diagnosis

Made from the history. An examination is offered but never insisted upon, and a clinician who understands the condition will not attempt one that the person cannot tolerate. Where examination is possible, it looks for skin conditions, scarring and infection, and assesses muscle tone. In a small number of cases there is an anatomical factor, such as a thickened hymenal remnant or a septum, which is why an unhurried look is worth having when it can be managed.

Treatment

Treatment is a sequence and it works. The individual components have reasonable evidence, and services that combine them report good results for most people who complete a programme.

Understanding the anatomy

A surprising amount of progress follows simply from accurate information: what is where, how much the vagina can accommodate, and the fact that it is not a fixed tube. Looking with a mirror, with no expectation of doing anything else, is often the first task.

Breathing and down training

Slow breathing into the lower ribs with a long exhale lengthens the pelvic floor. Learning to consciously release the muscles, and to feel the difference between contracted and released, comes before anything is inserted. This is the same work described on the overactive pelvic floor page.

Graded trainers

Vaginal trainers, sometimes called dilators, are a set of smooth cylinders in ascending sizes. The method matters more than the equipment: start with the smallest, use generous lubricant, insert only as far as is comfortable, and stay still while breathing until the muscles let go, rather than pushing. Sessions are short and frequent rather than long and occasional. Size increases only when the current one is genuinely comfortable. A water based lubricant is usually recommended for this work because it suits repeated application and washes away easily, and retailers such as inWonderstate list them as a distinct category rather than mixing them in with everything else.

Progress is not linear. A bad week does not undo the work, and returning to a smaller size for a few sessions is a normal part of the process rather than a failure.

Pelvic health physiotherapy

A physiotherapist who works in this field can assess tone, treat tender points manually, and supervise the trainer programme so that it progresses at the right rate. This is the single most useful referral for most people. See pelvic health physiotherapy.

Psychological support

Cognitive behavioural approaches address the fear and the anticipation that drive the reflex. Psychosexual therapy is appropriate where there is relationship strain, and trauma focused therapy where there is a relevant history. Involving a partner in some sessions is often helpful, since partners frequently interpret the difficulty as rejection.

Medical measures

Topical anaesthetic preparations are used in some services to reduce entry pain during trainer work. Any underlying skin condition, infection or dryness is treated in parallel.

Cervical screening

Screening can usually be completed with adjustments: a smaller speculum, self insertion, a longer appointment, lying in a different position, or in some programmes a self collected sample. It is worth asking directly rather than avoiding the appointment. See sexual health in your thirties.

Timescales

A structured programme typically runs over several months. Rushing it is the commonest reason it fails, and there is no benefit at all in enduring pain during the exercises: pain confirms the reflex rather than overcoming it.
