Hi sorry to hear you are having such a hard time - seems like once our bodies immune systems get compromised - we are subject to more and more - on your job - I cant remember - are you using your FMLA leave? Now is the time to act quickly if you arent to protect it - before your employer can take any adverse action... also, if there is a short term disability policy - I'd file right away (or if your state has short term disability separate from employer) - you need time to give your body a chance to recover some and hoepfully you can get that....

Hang in there - and hoping surgery goes well....
