Colic, help

Lindsey

My 5, almost 6 week old, has been having screaming fits for the past 3 evenings. Nothing calms him. Eventually he passes out cause he’s so exhausted. I don’t know what to do. I try to nurse him and he just screams louder, which is breaking my heart and is so frustrating. He won’t latch on at all. Is this colic? I try gripe water and gas drops, neither helps. Rocking will sometimes get him to stop for a little bit but he starts right back up as soon as I put him to my breast. I’m at a loss. Help please
