17 week old stuffy nose..reflux?

[Kazups22]

Hi all. My 17 week old dd has been waking up at night screaming with a blocked nose. This has been going on for 3 weeks and have been using saline drops, snufflebabe and calpol plug in as i thought was a cold. It has been difficult but have been getting through it by napping with her doing the day. However now it is effecting her during naptimes too! Its usually after feeds as she is fine in between. Has anyone had experience of this? Should i see GP or will it go away? She has milk silent reflux as a newborn but this improved hugely by 3 months. Thank you
