Oh Jenny

- I'm so sorry Momo is having symptoms that might be related to the heart. I don't have advice, except to say that if you can see a Cardio - that would get you the very best and most specific information. Cardios will know exponentially more than a generalist, when it comes to the heart...they will understand all the nuances that go w/ HF (heart failure) too...and there are many.
You two will be in my thoughts and I'm hoping for the very best outcome
