My mother who is 58 yrs old, 5-5 120 lbs is having tightness in her chest, numbness in legs sometimes, and shortness of breath, she thinks she has a pinched nerve also. Her doctors said it could be a result of general anxiety, and she has been diagnosed with the early stages of osteoporosis and they suggested ischemia to her heart, lack of oxygen I gather. What tests can be done so that she can find out once and for all what it actually is? She had EKG tests, came back regular in terms of her not having a heart attack after she had an episode where she had to pull the car over and EMT had to come and take her to the hospital. She had blood tests, cholesterol is fine; EKG was fine; but they said she was experiencing signs of ischemia at the hospital, which from my research seems very serious, but only told her to take asperin, and xanax for the anxiety. Does anyone else have a take on these symptoms? Could the tightness, or heaviness in chest be related to a pinched nerve more than a heart disease, or build up in the artery? Any help or suggestions for tests would be appreciated.
