I'm developing an unpredictable 'flutter' in the middle of my chest. It's been happening for a couple of months. It feels strong enough to be unsettling, but it's not my heart, that's been checked. It's not indigestion either - it doesn't seem to be related to eating at all. It's like a distinct 'rippling' feeling. It's not deep enough to be my heart, it feels much more like it's half-way up my windpipe.
It doesn't seem to be any particular time of day or activity, and doesn't seem to have any warning signs.
I don't know if it's Parkinson's related, but I've been diagnosed for four years and I have plenty of other symptoms, so I thought I would ask if anyone else has anything similar.
