Hi SueT 
I’d thoroughly recommend to try it, having done many similar things and knowing that it can hardly harm (if you can afford it). If you’re lucky it can help you with all your local pains and thus quality of life, maybe not Ache, stiffness and fatigue though.
I think it’s good if you get an impression of it before you go, so as not to expect too much directly whilst it’s being done, rather than in the days afterwards:
I’ve listed the Bowen technique in my treatment list along with what 2 people mentioned positively 9 years ago on here. The main caveat wikipedia describes is that each practitioner will do it in a very different way and may have little training or experience (or a lot), which I don’t see as a problem.
I’ve done loads of different types of manual (and other) physiotherapy, partly because I had different ones in the fibro clinic, but also because my many practitioners used a variety of techniques. I’d say each practitioner might have something helpful for you, and personally I would recommend you trying it, especially as at least it is a form that can’t do much harm. (As a contrast many things I tried did do harm, however it wasn’t always possible to know that before or during.)
My main experience is that all these types of manual therapy, mainly acupressure, expert or now self-applied were able to decrease my local pains to almost zero, which greatly increases my quality of life. What I’d hoped but they weren’t able to do is to decrease my overall Ache from overdoing it, my stiffness or my fatigue. The physiotherapy that helped there off and on was whole body cryotherapy.
Looking at my manual therapy list on my treatment list I’d recommend absolutely all of them, if you haven’t yet and get the chance:
Body Realignment
Bowen Technique
Connective tissue massage
Dry needling
Manual therapy generally
Myofascial release
Myofascial trigger point massage
Osteopathy (incl. Counterstrain, Positional Release Technik PRT/Jones Technik - gentler!, craniosacral therapy = CST, visceral therapy, parietal therapy)
Postural Integration (form of body psychotherapy, cf. Gestalt therapy)
Reflexology (incl. foot reflexology, ear reflexology like ear-acupressure and ear-acupuncture)
Rolfing
Scar and Bonework (Sharon Wheeler)
Shiatsu (Japanese form of massage)
Trager approach
Same however goes for all physical therapy, meridian system therapies (acupuncture etc.), or even more generally all the physical treatment forms I list - and actually everything I list except meds…
