If you HAVE got a broken rib (which I'd sincerely doubt - they bend quite a lot and you'd have felt one snap ... plus I suspect you'd be whingeing even more then normal.............
) all they'd do is strap you up to minimise the discomfort until it knits. There isn't any quick-fix for ribs 'cos they ain't easy to get at. You can't exactly whack one in a sling, can you?
It hurts when you move because they flex and bend along with your corpulent and flabby frame. Seemples!
By all means take Ibuprofen - same name over there and available from any Farmacia - try 600mg a day - to reduce inflammation, and after about 3 days you'll be fine.
EDIT: PS. Why have you recently started.
On the Clubshot-style, punctuation.
It's very. strange.
