I have recently been diagnosed with MVP and have moderate to severe regurgitation. I have been feeling like my lungs are filled with water...or I can t take a deep breath...it s not unbearable, but it s uncomfortable . I am a teacher, but during the summer I am bar tending. I walk about 10 miles a night at a very fast paced bar, and I m not winded then. I feel as though I m in shape... But in this humidity I feel tight in the chest, or like I can t get a full deep breath. Is this normal?
