Recurring Fever Even After Antibiotics Course, Lump Size Node In Lower Back. Low Hb, RBC. Treatment ?

Thanks for posting your query.
Prolonged fever for more than 3 weeks without a specefic usual cause is termed as pyrexia of unknown origin (PUO).
PUOs are caused by infections (30-40%), neoplasms (20-30%), collagen vascular diseases (10-20%), and numerous miscellaneous diseases (15-20%).The list of possible causes is very long, the more probable ones in his case being ,
Abscesses
Tuberculosis
Fungal infections/Parasitic infections
Lymphomas/Leukemias/Solid tumours
Collagen vascular and autoimmune disorders
Endocrine disorders
The exact cause can only be established after extensive diagnostic evaluation by his doctors, which in his case is most probably an infection .
Considering his present blood tests it his advisable that he undergo the following investigations as per his doctors advise
1.A blood and urine culture test.
2.A CT scan of abdomen and brain (to rule out post surgery long term complications like infection or abscess)
3.A fine needle aspiration cytology of the lump he has (most probably a lymph node)
4.A mantoux test for ruling out lymph node tuberculosis.
I hope his doctors would come to the exact conclusion soon.
Please do not worry as many of these causes are very much curable conditions.
Hope I have answered your query.

Answer 1.Yes the Crp is mildly raised which may be sugesstive of viral infections or any inflammatory condition be it immune related or infective.The normal value is usually less than 10 for most healthy individuals.
Answer 2.There is a possibility of the lump being a hematoma due to the rocephen shot which is known to cause local thrombophlebitis however it should show some decrease in another weeks time.The indentation could be due to it's fixity to skin and underlying tissue.But it does not rule out the possibility of an abscess or lymph node.
Answer 3 There is a possibility that the present complaints are unrelated to the brain surgery, nevertheless an MRI brain and spine is indicated if all other work up is negative to rule out neurological cause of the PUO.
Answer 4.Since the most probable reason for his complaints, fever, night sweats , lump, pain etc can be a viral or chronic bacterial infection it is good to get an opinion by the infectious disease specialist.In that case further investigations can be postponed till his consultation and advice.
