dear Caz,

I understand your concern BUT I would trust your physiotherapist.... she/he is the one that will get to know you best and will be able (or at least try) to answer all, or many of, your questions.
The more people you ask ( as in this forum) the more answers you will get.

Can you imagine that, not only because of cultural differences, but also because of differences in basic+ postgraduate education and interests, physiotherapists are not all the same.
It is possibile that they will have very different opinions and give you different advice.

Good luck with your treatment

Esther de Ru
