Thank you Patchouli - for answering that - you said that much better then I could have. Suppose, with all medications there are side effects and with cortisone I have only heard bad sides. I was just surfing and found so much on it - seems taking cortisone orally is worse than the injections. As in everything else, good and bad affects are reported, depends how bad on which site you are on.
Just to give you guys some more, I just found a thread on a tennis forum, has been going for a few years and has good, as well as bad stories and links to other websites on the same sunject.
Might be of interest but it is quite long!
