<s>[INST] I have experienced a very brief pinching over my left chest when standing on several occasions today.About a year and a half ago,I had my heart checked out through wearing a halter monitor and an EKG and was told I have a very healthy heart. I also take 2.5 mg lisinopril for BP which is well controlled and exercise daily. I am a 50 year old female. Is it likely anxiety produced? [/INST] Thanks for your question on Chat Doctor. In my opinion it is likely to be related to anxiety only. But since it is left sided chest pain, and you are known case of hypertension with age of 50, I advise you to get done ECG and 2D Echo to rule out cardiac cause. If both of them are normal and your BP is well controlled than your symptoms are due to anxiety only. So avoid stress and be relaxed and calm. </s>
