My mom, who's 55, got a pimple on her neck last month. The doctor recommended a Mantoux test, and from the results, they mentioned she might have skin TB. The thing is, except for that pimple, she doesn't have any other symptoms of TB. I'm wondering if just one Mantoux test is really enough to diagnose TB, or should we be looking into more tests? And also, is skin TB something that's curable? Would love some guidance on this.
