Hi. I am a 55 yr old female who yesterday had 3 briefly faints which was strange to me. I had tunnel vision, completely wet, instant flush and pins and needles in my hands and feet. I also suffer even now with very achy muscles in arms, back and legs. I was not stressed at the time, very relaxed, do not take any meds, was not dehydrated or have low blood sugar. I was taken to emerg and they didn t find an answer so I went home. I have been exhausted ever since. Worrisome to think this happpened to me. Any thoughts?
