Hi Paul,
You're absolutely correct in your thinking, medical opinion on intramuscular steroids does vary. It usually depends on the condition being treated and the severity
of the problem - it can even be given daily if necessary, but all regimes would be considered 'correct' for a individual case.
I am sure there was an article somewhere on the forum that highlighted the benefits/effectiveness people found. As I said, it has helped me but not as well as I expected,
it has also given me very disturbed sleep ( a side effect) - talk about brain in gear at 3a.m

Hopefully someone will point me in the right direction.
Thanks for replying
