[|Human|] Hi, last night when I was gettin ready for bed I laid down on my back, all of a sudden my chest tighten up, started to have shortness of breath and my upper stomache started giving me pain. So I decided to lay on my left to see the difference but it made it worst for me to breath. I laid my back again and I started to have lower back pain... Whats wrong with my body?
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Sudden onset chest tightness, shortness of breath at night while lying down (orthopnea) is commonly seen with heart diseases. So better to consult cardiologist and get done blood pressure monitoring, ECG, 2d echo and stress test (trade mill test). You may need antihypertensive and other cardiac supportive Chat Doctor.  Avoid stress and tension, be relaxed and calm. Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
