Hi, may I answer your health queries right now ?  Please type your query here... I woke up with a severe headache, shortly thereafter I got a seering pain just below my left shoulder blade which is now permeating to an area inside my left ribcage.
Thanks for your question on Chat Doctor. I can understand your concern. Sudden onset left chest pain, shoulder pain and headache should always be evaluated for hypertension and other heart diseases. So immediately 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.  If all these reports are normal then no need to worry about heart diseases. Sometimes musculoskeletal pain can also cause similar symptoms. So take simple painkiller like paracetamol or ibuprofen. 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.
