Hello doctor,my mother is having very high esr count,which 115 now.Last month she was admitted to the hospital as she was suffering from joint ache,fever,and sore throat including coughing and very low appetite.Now after one month she is absolutely fine,she is having good appetite now,no fever,but milg coughing is still there .But the esr count is still the same,that is 115.My question is what is the problem and how to reduce the esr count?
