Working as an osteopath i guess i should put my point across....
Osteopaths and Chiropractors can be very similar....depending upon the practitioner, because all practitioners are different in how they work to some degree..... as my most commonly asked question is "What is the difference between an osteo and a chiro?" i often say their might be more difference between 2 osteos than between an osteo and a chiro......
However, (here is where my bias kicks in) chiro's often focus directly on the spine as the root of the problem and they have slightly different ideas about how problems develop in the body and, therefore, how to resolve them.....chiro treatments may be 2-3 weekly initially, which i believe is far too much (& too much for people to pay)....the body needs time to adjust after a treatment and for the healing process to work on it's own....also, chiropractors may focus alot on manipulation (where you may hear a click or pop from a joint)....and this may not be the right approach for the problem or the person....many people don't like the idea of this approach...although it is very safe when used by a skilled practitioner.....It is useful to have a range of techniques to use to address a problem, not just manipulation....
Many people may think that manipulation can cause more problems than it fixes and i guess with a very poor osteo/chiro (hopefully rare) i guess if you were very very unlucky you could feel a slight aggravation of your problem but go ask a GP how many people have suffered at the hands of anti-inflammatories.....i can as i am married to one and she agrees....

Go on recommendation....the best way for sure...
Treatment sessions with osteos are often 1 hour initial consultation and 30 mins follow-ups...but again this can differ. I charge £35 initial visit and £30 follow-ups....this can be higher down South...
All osteos are registered with the General Osteopathic Council (GOsC) by law and are fully insured and closely regulated. Training is a 4-5 year BSc Hons degree (or BOst for some) with extensive medical & clinical training from the outset....many don't realise that we need to have the same skills as GP's in conducting medical exams and diagnosing problems....except we don't learn so much pharmacology at all...only a little. It is important to have this knowledge in order to identify problems that can't be treated by osteos and need to be seen by doctors elsewhere....in truth as i don't conduct CVS / Abdominal / Respiratory exams everyday i send them on to a GP if i'm not comfortable with a presenting problem as GP's are much better at these kind of things....
I must qualify that i know lots of chiropractors and many of them are very good and they don't all work as i suggest but many do....and of course you will find osteopaths that aren't as good as they should be....like any profession their are good, average and bad...
Bottom line....go and try osteo (or chiro for that matter) and see how you get on. If you don't feel comfortable then don't go back....but a good osteo should answer all your questions, put you at ease, and most importantly help you with your problem if they can in an honest and professional manner. If they can't help they will advise you where to go as the next step..... Just remember that it can take a few treatments to notice the difference, especially if the problem has been bothering you for a while....i usually say try 3-4 treatments to see if we're headed in the right direction but i always talk through experiences visit by visit....but you may only need 1 or 2 visits....
The problem with the NHS is that waiting times can just prolong a problem and many NHS physio's may see you for 10 mins and hand you a sheet with exercises on it to do at home....no hands on....little help especially for those that don't do their exercises (which can't be blamed on the physios!!). Private physios are different and they have more time (not being on NHS time) so treatment may be more thorough/extensive.
Anyhoo....where did that come from.....rant over
Good luck and i hope ur feeling better soon!!
