chest vibration when taking a deep breath after sleeping

Hi all just wondered if anyone has this? Every night for the past couple of months, when I wake up and sit up in the night, I take a deep breath in and feel this vibration in my chest.It is only on a deep breath. It usually clears after a breath or a few breaths. I have no cough and doesn't feel like it is coming from my lungs but I can't be sure. It is the strangest thing! Thanks all

Hello, did you ever get to the bottom of this? I have the exact same. I had a baby 8 weeks ago. Thank you xx

Hi. Thank you for your reply. I was beside myself with worry. Last night I couldn’t sleep and googled it and I’ve seen on quite a few posts it seems to be quite common after pregnancy/birth. Someone said that it is from where baby put pressure on the diaphragm which makes sense I guess. Mine started in pregnancy. It’s easy to forget what weird things pregnancy does to your body!
