I had chest pains, back pains going up to my throat and neck, tropamine in my blood. Heart rate 90 bpm. High blood pressure. An ambulance took me to hospital, 4 days of monitoring and an angiogram and echo. They do not know what it was.Still feel washed out and tired with a pain in my chest like I have been kicked. I am a fit 58 year old woman. Was diagnosed with BC in 2010 had chemo, radiotherapy, Herceptin.... and am on Tamoxifen at the moment.
