That's a good question. It's difficult for others 2 understand ur challenges when they haven't been thru it themselves. Physical therapy is what u'll need. Let her know that ur needing 2 do things in a safe and healthy manner. Depending on the reason ur having back issues ur Drs will need 2 set an exercise regiment. I myself suffer and have CFS so exercise makes me crash hard. Still get those comments tho. I try and tell them my issues then try deflecting, if that doesn't work then ignoring is the last resort. Who needs anyone badgering u when u know ur own body.
