[|Human|] My husband has dissy spells, somtimes on waking. Today he was gardening and had a sudden attack of dissiness, nausia and vomiting. He says he feels as though he is sea sick. He also complained of a sudden sharp pain in left back of neck. He had open heart surgery in 2004 to replace a bicusbet ascending aortic valve and a portion of damaged aorta. (please excuse spelling). These spells have been more frequent the last two weeks. We saw a new doctor today and he is going to fit him with a heart monitor on Friday. I am worried, could he be having small strokes? Or trouble with blook clotting?
