Rach, I'm busy with my dog right now but had to respond to your post 'cause it scared me. My dog has a tooth abscess and infection and I'm worn out.

Those vertical dents are from a lack of oxygen. I have them too. They are called Beau's lines. That combined with your chronic kidney infections and the splinter hemorrhages, make me concerned that you do have subacute bacterial endocarditis (as Mrs. D. has pointed out is a serious cause). If you are having damage to your heart from an infection, that might cause your hypoxia as well.

You HAVE TO go see a cardiologist as soon as possible. None of this UK socialized medicine waiting around for six months for an appt. When was the last time you had an ECG? Have you ever had an echocardiogram? Sometimes, and this was the case with a friend of ours, they have to do a transesophageal echocardiogram. It's where they go through your esophagus to look at your heart. With your GI history, and MG, that may not be a wise thing to do, however.

Please get this taken care of right away!! You'll be in my thoughts.

Annie
