or just AM

if you mean that you slept in a way that made you sore, then that would be one way to capture the idea

My back, and shoulder are hurt asfrom sitting too much.

So I decided to not only usinge Pomodoro, but also remindto remember that after every session, I should stand up for a little bit rather than nothing.

if it was a past decision, then "decided"

Sh*t, my back is kickhurting me out, telling me thato stand the f** up or lie down oin bed, p. It also says, "Please don't sit on this chair for that long, he's bout to die."

sometimes we say "my back is killing me"

Phrased more naturally

Make it plural "shoulders" if it is both shoulders that hurt

So I decide tod not only usingto use Pomodoro, but also reminder that after every session,to set up a reminder to stand up for a little bit after every session rather than nothing.

Phrased more naturally

Sh*t, my back is kick(screaming at me/forcing me out), telling me thato stand the f*** up or lie down on the bed, please don't sit on this chair for that long, that he's about to die.

Kicking someone out is really about removing someone from a building, but I gave a couple of other options here. "Kicking off" also exists about removing someone from being "on" something, e.g., "My brother kicked me off the computer," but unless you are going to mention -what- you are getting kicked off from, I wouldn't use that phrase either.
