If tuberculosis shows negatibe in everh test..But all thr symptoms supportd it...Doed TB medicine is advisable?

Symptoms ?: In the US TB is treated with multiple meds at one time due to germ resistance and for months to years. I could never recommend such a treatment based only of suspicion & no verified testing. There are many alternative conditions that produce the vague symptoms often seen with TB & these must all be considered. ...Read more

My son had tuberculosis when he was 9years old. His coughing however sounds really bad. Is it possible for TB to have a relapse?

My son had tuberculosis when he was 9years old. His coughing however sounds really bad. Is it possible for TB to have a relapse?

Tuberculosis: Although the first thought may be a reinfection, it may not be probable. Your son is probably as healthy or healthier than his peers (malnutrition is often associated with tb). He needs a consultation with his primary care physician or pulmonologist. If necessary, a chest x-ray maybe indicated. My feeling is that he probably just have a bad cold (or whooping cough). ...Read more

Can treated TB lymphadenitis pass to fetus or can baby be born with tuberculosis?

Certainly you need close follow up care with your doctors to help you and your baby through this critical time. The good news is you're on meds, which means the bacteria are being destroyed. Take care. ...Read more
