Dear manjeet , Idont know whether you are a male or a female, but if you are a female then a mild variation in your ESR
during or just before your menstural cycle is acceptable. ESR is a very non specific test and does not signify any disease in particular but rather a presence of some pathology. You should get yourself investigated in detail with a healthcheckup plan which includes your blood tests urine examination, stool examination, thyroid
profile and basic USG and x-ray of chest. Visit your general physician with the result and do not get so stressed up about a raised ESR value. Relax and take care.
