i am suffring from low grade fever since january 10th 2013. My other symptoms are burning sensation in feets. The burning in feet is before starting ATT. Frequent sore throat. Frequent sinus congestion. Dry Cough. Fatigue and extreme weakness, 6 Kg weight loss i a month. I got tested for HIV(Negative), HBV(HbsAg)(Neg),HCV(Neg), Serum protein electrophoresis, ANA, pANCA, c ANCA. My Hemogram shows WBC elevated and low Lymphocyte counts. My CD4 count was 430 and CD8 count 350. I am taking antitubarcular treatment since last 2 and a half month due to a positive TB gold test. But fever still persists. Can there be some other conditions responsible for this.
