Disclosure
• We are not pain specialists by training
• We seek support and advocate for our pain program and its patients
• There is very little evidence supporting our practice

What we are hoping you take home…
• To recognize some elusive causes of chronic pelvic pain, when other causes have been ruled out
• To gain skill performing a pelvic exam for chronic pelvic pain- as it is the single best diagnostic tool!
• To develop an approach to chronic pelvic pain, from diagnosis to simple initial treatment plans and other resources
• When to refer to chronic pelvic pain program, and what we provide to our patients

Myofascial Pelvic Pain
Common painful condition
…trigger points may be identified in as many as 85 % of patients suffering from urological, colorectal and gynaecological pelvic pain syndromes… can be responsible for some, if not all, symptoms related to these syndromes…

Myofascial Pelvic Pain
• Short, tight, tender pelvic floor muscles (hypertonic pelvic floor)
• Myofascial trigger point• Focus of hyperirritability and pain in a muscle.
Persistent fibre contraction
• Twitch response
• Refers pain on direct compression
• Referred autonomic phenomena

Vulvodynia
• vulvar pain of at least 3 months duration that has no identifiable cause
• further subdivided by:
• Location – The symptoms can be localized, generalized, or mixed
• Provocation – Provoked, spontaneous, or mixed
• Onset – Primary or secondary
• Temporal pattern – Intermittent, persistent, constant, immediate

Vaginismus
• Difficult to differentiate vaginismus from provoked vulvodynia and it is likely that both occur on a continuum with some women having more of a prominence of pelvic floor muscle tightness symptoms and other women having a predominance of pain symptoms

Pudendal Neuralgia• Cardinal symptoms of neuropathic pain:
• Hyperalgesia• Allodynia• No sensory deficit
• The diagnosis is made on the basis of characteristic clinical findings that include:• Pain in the anatomical territory of the pudendal nerve
• Pain worsened by sitting
• Pain does not wake the patient at night
• Pain without superficial sensory deficit
• Pain relieved by diagnostic pudendal nerve block

Rule out other causes of pelvic pain…

Then focus on education and expectations
… it should be made clear that pelvic pain syndromes are chronic conditions in which symptoms are managed but are likely to be ongoing, characterized by periods of remission and symptom flare. Improvements may be slow, as there is not a treatment that is one size fits all, finding the correct treatment for a patient may take some trial and error, time and patience…

Pelvic floor Physiotherapy
• Primary treatment of myofascial pelvic pain
• Manual myofascial release
• Stretching
• Strengthening
• Physical therapy works!
• A small trial comparing PFPT and trigger point injections in women with MPPS reported >50 % improvement in symptoms for each group
• A retrospective review of 146 women with MPPS who received PFPT, 63 % of patients reported significant improvement in pain scores
Available in the community
