Over a year ago my mom had severe pain in her back and jaw, as well as shortness of breath and we took her ER. They took all the tests and told us she was having an heart attack. They proceeded to do an angiogram and found blockages, so they put in a stent in on her left side of her heart. She continued to experiencing pain in the her back and was not recovering well. They then did another angiogram and used a balloon to open a blockage that she had in her right side of her heart. After that procedure, my mother recovered well and did not experience any pain for about 9 months. Two weeks ago, she started to experience back pain and in her jaw late at night while resting. That is when all her other episodes had taken place. So we went to the ER and the took the enzyme test and cat scan and they both came back clear. Since then she has experienced two similar episodes and continues to have moderate back pain. They have done more testing and all have come back clear. We have been to the cardiologist today, and since the tests come back clear, they do not feel it is her heart. But she have never experienced typical chest pain, her symptoms have always been severe back pain and sometimes in her jaw. They are adjusting her medications, which include blood thinners, beta blockers, etc.-the usual combo to treat the heart. But, they have no answers to why she is feeling this way. I just wanted to know if others have experienced similar symptoms and if there was any diagnose or treatment for it? They have mention trying EECP treatment if nothing else works. Has anyone tried that and does it help? I'm just trying to find answers to what is going on with my mother. Thanks in advance.
