I'm taking an antibiotic in my vain at a rehab center. I have an infection in my knee and they had to operate and replace the pad and clean the knee out. (Had knee replacement several years ago.) I was getting it once a day until this past Friday. That day I was told I have too much of it in my blood so I would get my next dose on Sat. night. ( was taking it in the morning) They did not give it to me Sat. night. Today (Sun) they tell me I will get it on Monday and not any today. My knee is hot to the touch and I do not feel well at all today. Does this sound right to you?
