My GFR goes from 115 to 85 after one year and GFR category from G1 to G2. Creatinine is 1.91 and billirubin direct 0.35 and billirubin total is 1.10. Other tests like thyroid,diabetes are within the range. Is it some kind of early kidney or liver damage sign? If yes, then what should I do? My platelet count is also goes down from 247 to 170 and mean platelet value from 10.7 to 12.7. I am taking revital women from the past one month and tests are done on 3rd day of my periods and I am having little sore throat but I am not taking any medication for it. Can it be related to this? I also feel pain in back of the foot heel while walking. What can be the reason for this?
