Reports showing high crp & esr, low ferritine & vitamin d, slightly increased lymphocytes, normocytic hypochromatic blood picture, what does it mean?

Inflammation: This shows that your body is suffering from an inflammatory condition but does not tell us why. This is most likely an autoimmune disease and/or chronic infection (which could be a virus, bacteria, parasites and/or fungal). You need further testing. Take enough Vit. D (about 5000 iu/day) to bring D levels to 50-80. Get further tests but also I'd also consult a homeopath and Ayurvedic practitioner.
