So many times I've experienced that the nurse(woman) asks me to lie down and get ready. I lie down and take down one side of my pant(left or right buttock) and wait until she comes to inject it. When she comes she takes down that side more and also tries to take down the opposite side too so that my buttock cleft to be seen by half.
Why does she do this? Is it really necessary? Should I get embarrassed?
