I have a quick question about the situation my friend is having as I am not too sure if I am allowed to massage her back at all.

Basically my friend is suffering from the big lower back pain and when she did the back x ray, her doctor confirmed that she is having a PSOAS Syndrome (her right side muscle is ripped). I read about this Psoas syndrome thing, however I am still not too sure if the lower part of the back could be massaged even gently without applying any pressure?

Thanks,

Oksana
