You can use sick time if its at least half a day. I got approved for 1
year of FMLA and have to have it redetermined in
a year. But mine is for multiple health issues, as I am also diabetic. When I went thru treatment 13 years ago., I do not remember missing a day of work. Just for dr appointments that I had to keep. I would wait and see how you feel.. remember it effects us all differently. You may have a mild one. I wish you the best of luck and hope you reach SVR.
