Hi Weepea
I was taught that reflexology, apart from when there is contra-indication, can do no harm.
I believe that reflex helps with all conditions medical or otherwise, but I do not agree that this means I should believe that they aggravate them too.
Reflexology is incredibly gentle and balancing. More to the point it is the body which is doing the healing anyway, the treatment and practitioner simply provide the correct 'environment' to facilitate the body's own natural healing.
Reflexology isn't the only factor involved in the healing and so I do not think it can cause any harm by itself. As long as a client is treated holistically and as an individual I do not believe that it can worsen medical conditions.
With regards to your other question - yes reflexology helps, and you should find out why and how etc during your course. Have fun!
