Neck twinge

So literally the day after I found out i was pregnant, I got the twinge from hell. I think it's in my back radiating into my neck. My neck is stiff and the pain is almost unbearable. My friend whos physical therapist has tried to apply pressure to this knot in my back which gave me some range of motion back but then the next day, the pain came with a vengence. I cant really do neck rolls at this point, it hurts too much. I decided to try hot and cold compresses and when that didn't work, I tried that in a warm/cold bath and the pain actually went away but come the next day, its back again. I've tried changing my pillow, drinking a lot of water, taking Tylenol, but nothing helps :( it even hurts to breathe. Any advise?
