I'm not sure if this is a CFS thing or if I'm just sensitive, but my body really wants to pass out during medical procedures that involve puncturing the skin, including blood tests. Oddly enough, I'm fine with other painful and invasive tests that involve using already-existing holes in my body! Today I had a small skin biopsy. I was lying down, I had a nice local anesthetic so I didn't feel anything, and I wasn't looking. The procedure went well, the nurse finished, and then all of the sudden I felt all of the blood leave my head. Thankfully I didn't pass out (which I have done on a few occasions) and recovered after a few minutes. I felt pretty pathetic, but thankfully she was nice to me. I need to have another procedure tomorrow that involves a lot of needles. I'm only slightly anxious about the procedure itself, but I am terrified of fainting or getting faint. I absolutely hate that feeling of being on the verge of fainting! Do any of you with similar experiences have any tips and tricks for dealing with this, other than lying down?
