My friend is going back to work soon and will be expected to be able to check patients' pulses on a regular basis. She is trained to do this however when she was pregnant she found that she can feel a pulse in her own fingers so when checking someone's pulse she is really feeling her own! She knows this because if she places her fingers on any non-living object she can feel a pulse. She thought after the baby, it might not happen anymore but it still does.
Anyone else had any experience of this?
