Hi everyone: yesterday I had the most horrid experience. This breahtless prob has been going on for two weeks on minimal effort! Yesterday, I tried walking a few steps away from home towards a little newspaper shop accross the road. I felt very unwell, when I arrived in the shop, I felt pressure in my chest, dizzy, nauseaus and asked for a chair to sit on. The I noticed my nail bed in the left thumb turning blue. I called a taxi because I could not stand up and went to A & E at a hospital. Doc did and EKG which came up 'normal'. He said to go to my GP on Monday. Yet the GP knows that I went to hospital for the same problem a few days ago, but did not have the blue nail bed. I sent her the report from the first A & E visit and wrote to her explaining that I was feeling very unwell and was homebound. I also asked her if I would be sent to a respiratory specialist or other. Still she has not contacted me! Does any one know out there why could the nailbed turned blue in the left thumb? Could it a temporary arterial spasm, or perhaps could it be related to the pulmonary artery or asthma? I am quite debilitated and incapacitated. I am a little annoyed that the GP has not contacted me. On the other hand, if I do phone or go to her, she might well be annoyed and stike me off her list..... as this seems to be happening quite a lot to others. An echocardiogram revelaed an ejection fraction of ~ 50% which is below normal. Mild MR (am not sure what this means), was told had a little left ventricular dysfunction (not sure what that means), a normal thallium scan four years ago. Abnormal T-Wave flattenings on ECG's several times upon chest pains and nausea. A stress test at sub-optimal level (I could not run very much was too breathless) was fairly normal. Hotler Monitor showed slow pulse or tachycardia up to 150 bpm. Was discharged from the Cardiology clinic and told that there is nothing structurally wrong with my heart! I was told by the doc yesterday at the hospital that there is no way I could have developed arthesclerosis of the arteries so fast since the tests revealed no gross abnomalities. Does anyone have any experience of the above, in particular the nailbed of the left thumb turning blue upon being breathless, chest pressure, constriction and nausea? Would be grateful to hear your views on this disturbing new symptom..... Looking forward to hearing from you. Many thanks. Kooky.
