Hey everyone, so I have suffered from anxiety and health anxiety for a number of years. The last few months have been particularly stressful and I have been fighting against heart worries as usual. One thing I have started doing though which is new for me over the last few months is tensing my stomach, which has essentially caused pain, tightness and like a burning feeling inside my stomach and throat and sometimes have burped up food. Is tensing and bad posture something that could contribute to acid reflux?

Thanks
