Good evening my mother has had a water infection and has had anti biotics to combat this . She was running a temperature at the time and was feeling tired and lost her appetite to eat . The gp asked her to go for another urine test and blood test. Her urine test was almost back to normal and the temperature has gone and she s got her appetite back. The bloods were showing that most things were normal but her iron was a little bit lower than normal but her Esr level was at 90. He asked for her to go for a chest x ray which has come back as normal but would like her to have another blood test next week to see if the Esr levels ,reduce. Is the high Esr due to her having a water infection?
