So as I posted the other day I started my first day as a CNA today at a hospital. OMG! my body feels like it is going to fall apart, i even cried after my shift walking to the bus stop because I was so weak and my body from my lower back to the tips of my toes were in so much pain. Even though I'm only 20 I have always had lower back pain when I stand for too long. The CNA that I was orienting with today said that she just got used to it. She's in her 40s and a little bigger than me but it didn't even effect her she seemed just as fine as when she started the shift I couldn't understand it. i'm going to go stretch and I will start doing some back and thigh exercises to strengthen my body. I started working out not too long ago b/c I'm 40 pounds overweight (but even the people bigger than me don't seem to be effected). Any advice about how to deal with severe pain after a working in this field?
