Hi guys twice today I had a random chest/upper back pain while I was getting up from laying down. As I move, there is a SUPER painful ache inside my chest and upper back (all over the area). However, when I stay still, it goes away. It lasted for like a minute this morning like that and happened just again how for one minute. I could move like the slightest inch and there’s a super bad bad interally. I’m just scared as to what’s causing this. I’m 17 and I had an ECG and holter monitor test that were both fine. Could I maybe have pulled something while getting up from bed? Idk im super scared.
