The last couple days I've noticed that on movement, especially when bending down, leaning forward etc that I feel what feels like a pop in my sternum (in the v shape between boobs and upper stomach). It's not painful just a weird feeling and more annoying than anything. What is it?!? It's freaking me out and I have super bad health anxiety which isn't helping. I did have this kind of thing once before way back after my son was born and he's nearly 2. Id forgotten about it until it happens again the last few days. It's everyone I move and got to the point of being scared to move in case it's something serious and it pops again. I plan to go to my GP but number one, I don't want to make a nuisance of myself at the doctor's of ots probably nothing and number 2 is just be interested to know if anyone else has had this really appreciate any advice or experiences of something similar and some reassurance. I've been going out of mind all day with worrying about it.
