Hi everyone: I had my valve operation back in Nov. 2016. I went back to work in March 2017. I have been noticing that when I lay down or get up sometimes, I can hear my chest bones clicking a bit. Is this normal? I thought I would be heald by now. Should I not hear any clicking eventually. I am just worried that my chest would come apart. What should I do? This has got me worried. My job is very physical, climbing ladders and telephone poles etc. Opinions please!
