Muscle contraction after blood donation
I just went for a blood donation for the first time today. The doctor told me to relax before taking blood. During the blood draw, I felt dizzy and nauseous. After the donation, my body became as if I were paralyzed, and I couldn't talk or breathe well. The nurses worked to relax my muscles for 15 minutes. then they informed me it happened because I was tensed. I was wondering just why the severe muscle contraction happened after a blood donation even though i m not tensed.
