Hello imran... you ought to know that ESR of 65 is certainly high and needs to be investigated further. I presume that only ESR is raised and rest of the CBC pofile is within normal limits as it would rule out anaemia . As your wife has recently delivered , back pain
n bodyache are common if your wife is not on calcium supplements
n raised ESR could have been an incidental finding due to some subclinical infection. But it is certainly important to rule out tuberculosis
. In the event of a negative report it would be wise enough to work her up for autoimmune disorders( rheumatoid arthritis
and SLE), especially if she has early morning stiffness
of joints or has facial rashes.
