With two of these episodes the symptoms were quite severe,
the first having slumped against my sister because
of weakness and almost fainting and
the second with blurred and fuzzy vision with an orange ring around it and almost fainting. Both episodes gave me a tightness or squeezing in my chest along with a building pressure. Once I feel that I am almost going to faint it passes, but I feel weak and tired afterwards. I check my BP and it will be high.
