<s>[INST] I am having some physical rehab done on a swollen knee. In the past few days, I feel a slight pressure in the middle of my chest, just noticable when I am quiet. Exercise doesn t seem to affect it, at least negatively. Blood pressure at vascular surgeon s office last week was 135/80. My pcp was concerned I had some blood circulation issues in my right leg. [/INST] Thanks for your question pressure in the chest can be due to- gastritis-cardiac issues- mediastinal issues you need to visit a chest physician or a general physician who can request for a chest X-ray and an ECG to evaluate and diagnose the problem in my patients I generally start them with proton pump inhibitor and investigate them continue with the medications and physiotherapythanksfeel free to ask more questions </s>
