I have been feeling a lot of tightness in my chest. A recent stress test showed that I have low probability. I was able to reach my target heart rate. I still have the pressure, mostly upon waking. I have had thyroid cancer and my medication was changed from Levoxyl (no longer on the market) to Synthroid (which I took for 16 years before being dx'd w/CA. Should I have further testing done?
