['I remember the one time my co worker took out his back , he would still come in to work but i made sure i did all the heavy lifting so he wont he eventually got better', 'That is some dedication.  Did he finally heal up?', 'took him weeks , but i just felt bad i worked with him for years']
I'm glad to hear that he is better now - you did a great thing by helping him.
