Having some issues with right clicking

This only started yesterday or the day before, I think it was yesterday. But my mouse keeps either ignoring right clicks, or double right clicking. More often it's double right clicking, making me place twice the amount of blocks, or splitting stacks when I'm opening a chest.
It's very persistent and makes it really difficult to play, any ideas?
 
I tried restarting, changing the amount of blocks rendered in game, turning my mouse off and cleaning it, unplugging my mouse, changing the batteries, changing the sensitivity on my mouse settings. I unfortunately don't know where my mouse drivers are, it's a wireless mouse and it just installed itself when I plugged it in, so I don't know what they're called or where they're saved...
 
I've had this mouse for years and this is the first time this has been an issue. It only seems to happen in minecraft, so I'm wondering if it's a minecraft issue, but I have no idea, and I'm not very tech savvy.
