My mother who is 61 yrs old is suffering from mild fever from past one month. Her ESR and CRP was 110 and 18 respectively, approximately a month back, now it is 104 and 14 respectively. her Montoux test result is also positive. prior to all this she was suffering from urine infection and was hospitalized also. Does all this indicates towards tuberculosis? If yes, then of which part, as in, her lungs X-ray came out fine, so what it can be?
