Is it unhappy, distressed, desperate type screaming or just loud noises? If its not a pain noise then it's most likely a phase and she will grow out of it. My dd was a terrible screamer until around one,especially if I was more than a foot away. It ended when she learned to walk at around 11 months.
Have you taken her to the doctors? If she's usually happy but has now changed I'd book her in for a check up to be sure there's not an ear or chest infection or something behind it. I've often found with my children that when they become wingey and won't be put down it turns out they're poorly x
