Thanks for posting your query to HCM You have undergone some investigation and didnt find any abnormality, but I wanted to know your complete blood count report weather it shows infection or not and what treatment have you had so far . I wanted to told you that in our country Malaria is endemic and many of the time it was not detected in routine test . In such condition on the basis of clinical diagnosis we should treat it . In my opinion your feature goes in favour of malaria so you should consult a physician in your area and received treatment for malaria along with antibiotics . feel free to contact if any query. thanks .
