What’s going on?!

I don’t know what’s wrong with my baby😢 he screams out of nowhere like he’s in pain. I checked his back and he has a lot of bruising on his back and left side of his thighs. His right cheek is also super red. I already checked and his temp was 98.0. I don’t know what to do or what this could be that’s bothering him ☹️ has anyone been through this? He’s 2 months by the way
