Sorry this is a bit nebulous!!! At times I get a weird feeling in my chest..breathing is fine..it almost feels like an allergy..I don't have hay fever or asthma...it makes me cough just a little. It comes and goes..there doesn't seem to be a reason, apart from having been at work today and I have it usually after exertion but not always. So sorry it's hard to describe but it's a bit unnerving. Am wondering if the connection is still being on low meds..am upping NDT gradually or an adrenal connection? It usually settles and just goes away but when I have it it's quite odd..my heart rate is fine. thank you.
