<s>[INST] good morning sir actually my father suffered with high level of esr .pls suggest how to control and what medicine is used for the treatment .because of this higher level of esr he always feel like having fever and also he is not able to stand for long time if he do this then he has to face legache .so plz sir suggest but to do ? [/INST] Hi. ESR is a blood test which reflects many underlying parameters in the blood, and is not a disease. There is no treatment available for elevated ESR, but the cause of the elevated ESR needs to be found and treated, which will reduce the ESR automatically when the underlying disease subsides. ESR is a non-specific test which can be increased in a number of conditions including infection, tuberculosis, malignancy, etc. So please get him evaluated as to why he has fever with elevated ESR and then get him treated for the same. I hope I have cleared your query. Thank you </s>
