I've been a CNA for about two month and I also hurt my back. I'm not sure how but I started to feel spasms after I helped a resident that was very nervous because she had fallen in the past. I was also advised to do exercises which I'm going to start today after reading the post here. I just quit my job at a nursing home because I felt like I didn't fit in and I couldn't trust some of my co-workers because they didn't like me. I just got another job and I start orientation tomorrow so I'm very excited to give this profession another chance. I was thinking of trying something else like a school bus escort, but I paid so much money for this profession and I'm glad I'm going to give it another chance.
