Dear Sir/Madam, I am suffering from T2DM and HTN for the last 2 years. Taking metformin 1000, sitagliptin 100 and dapagliflozin 10 for diabetes and tazloc beta 50 for hypertension. Due to chest pain I undergo evaluation about 1 year ago where my ECG, TMT,2dECHO are found normal only grade 1 diastolic dysfunction. But last few days around 15 days or more when I am laying down left side or right side after a few minutes I am suffering shortness of breath for some minutes. At night when I want to try to sleep, the time when I am in next to sleeping stage suddenly shortness of breath for a second and I woke up. That's why I can't sleep all the day and night. Please tell me what should I do sir... Right now No pain in chest, no swelling in arm or feet, nothing. But when I am laying down sometimes I am suffocating and shortness of breath.
