question: I had a pricking pain inside in the left lower arm portion and some occasional pain in the lower back side and some point and some sort of heaviness in my chest. I have some border high sugar but my cholestrol is OK. I took ECG and consulted a doctor and he told that there is not much change in ECG. This pain may be due to sugar increase. He advised me sugar control tablet and Sorbitrate and Ecosprin for two weeks. Of course the pain has gone, but occasionally returns. Why is this and what am I to do next. Please advise doctor
