Well I woke up on monday with the worst cold. By the time monday night rolled around I was so miserable I couldn't sleep. Went to the doc on tuesday because it had already gone to my lungs. She put me on biaxin 500 mg twice a day. And believe it or not it isn't helping. I had to test my inr this morning and I was thinking it might be a little higher than it was last week but it stayed the same at 2.7 which is great. But then I had quite a bit of foods this week with vitamin k. I've had a hard time eating and a lot of things have made me nauseous so I've basically been living on not much food but have been eating my salads and had my cabbage and corn beef for St. Patrick's day and had spinach dip last weekend too. So anyway I'm just thinking if I had not had all that food with vitamin K in it my inr probably would have been pretty high. Anyway the antibiotics don't seem to be doing much and I still feel awful. May have to make another trip to the doc as I have missed a day and half of work and not only can I not afford that but I have to watch it as management on my job only gives u 6 points and your out the door and I am already at 2 and 1/2. Anyway just thought I would share my experiences this week. And wondering if anyone else has noticed that antibiotics don't work as well after surgery?
