[|Human|] I am 49 years old and had a heart cath when I was 42 for a branch blockage. Other than that I have been pretty healthy.  I have hypothyroidism but it is under control.  A few days ago, I began having chest discomfort and left shoulder pain that has not let up.  My pressure seems to be up.  Should I go to ER?
[|AI|]  Hello! Thank you for asking in Chat Doctor. I can understand your concern. According to your history about your heart problems it would be better for you to go to ER. If I was your doctor I will firstly exclude cardiac problems by doing :Cardiac enzymes Cardiac ultrasound If these test are negative, then I do not think that this pain is related to the thyroid glands and the next step it would be:A CHEST X-Ray to rule out lung diseases. If it comes negative too may this pain can be due to stomach discomfort. The ER doctor will advise you further after he has the above results. I wish you a good health Thank you Chat Doctor.
