Hello doc, after dinner I walked for a while and after sometime when I sat down I felt mild sweating, body weakness, lightheaded and small blisters on fingers. I checked blood pressure one day before it is normal. I use to feel sometimes this problem. I also done echo, tmt and ecg 2 years back all came to normal. And recent ecg's are also normal. I don't know what's happening to my body. Is anything related to heart?? Or it's anxiety and stress issue? Should I repeat heart evaluation again? What are the additional
vitamin tests I have to do?? please suggest and please help...
