Yeah.

Dry coughing for a month, initially I thought normal flu, went to consult doctor two times. It keeps coming back after medication.
Difficult breathing (the feeling was like you never get enough oxygen inside you even you breath deeply).
Low fever, night sweat (even in airconditioning) still make my body sticky at night.
Sometimes chest pain.
Third-time visit doctor was the worst case.
Cough out BLOOD 2 different times

Good things to me were no chills, no weight loss, no loss of appetite for me.
Funny thing is I lost weight during treatment.... HAHA!!
But I think is because I stopped my gainer supplement after starting my TB treatment kot.

Haha, I cannot assure where and doctor not FBI too.
I met a few TB patients during doctor visit, I asked them the same question, their answer same as mine. "I have no clue~~ maybe this.. maybe that.."

Like you said yourself, you first experiencing the symptoms only as simple as nose/throat infection.

Person next to you that manifesting the similar symptoms would think the same to themselves, but turn out might be having TB as well.

Thats can be as simple as that, the subtle way of TB transmission from one to another.
