Original Raiju button difficult to press

Hi, I accidentally dropped my Razer Raiju 2-3 times (damn that cable) and now the triangle button is difficult to press. It seems to ease a little with continued use though... by which I mean, when I pick up my controller tonight the button will be very noticeably 'sticky' but within say half an hour it seems to have 'warmed up' so it's a bit easier (or maybe I just get used to it) - it doesn't depress as easily as all the other buttons though. Is there any way to fix this? Would rather not have to shell out $350 AUD for a new one, if possible. Thanks. :)
