I am a 43 year old make and I have Ehlers-Danlos Syndrome and sleep apnea.
For the past few weeks I have been experiencing an intermittent "prickly" feeling in the skin of my upper chest and sometimes arms. It is not usually related to physical exertion but came on this evening when I went for a walk up a steep 400 foot hill. Half way up l developed the prickly feeling and almost passed out from the fumes of cars passing by. It was quite a cold evening - whether that is relevant I don't know.
It was pretty scary. On top of this I have recently suffered a suspected retinal haemorrage in my eye.
I have put the question in this forum as I wonder whether these symptoms are signs of an impending heart attack. As a precaution I got my doctor to take my blood pressure and sound my heart. All OK. Equally, a battery of blood tests showed no cause for concern.
Googling this, it seems nerves could be the cause. Do I need to concern myself further over this?
