Patient discussion about electron spin resonance

Q. high ESR levels? i had ESR test done after complaining of weakness, repeated upper respiratory infection, fever and weight loss. my ESR rate is extremely high 120 a week ago and today 114. chest x-ray negative, stomach Ultra Sound negative, other test relatively ok.... Any suggestions?
