small gaming mouse for $20

[Zastonish]

So I got my mouse thinking it's what I need(Bloody a90) but the mouse is too big and my wrist hurts while playing and then I used a cheap wireless mouse and it was smaller and it made me use my arm instead of wrist to aim, which alleviated some stress on my hand thinking of swapping between the two since in fps games I don't use the side buttons often it's more of a bonus for me, Is there any suggestion for my new mouse?

 

The Bonus features is Wireless and side buttons that's don't need rgb or anything like that but the tracking though needs to be good enough it won't be glitching mid lift.
