I woke up really late and everything on my right side hurts whenever I move it.
Should I take a bath or something?

Try that but don't go too hot with the water. If it persists then you may need to go to the er. That could be something serious.

Rest, preferably on the other side.

You may have strained a muscle or slept in a weird position, this happens a lot with me. A bath is a great idea, if you have someone who can give you a massage preferably deep into your tissue then do that, if you don't you can always do it yourself. Take some pain relief but if it keep going and if you notice swelling then go to the doc

Yes, I'd the issue persists then make sure to come to me
