hello everyone.. i've already read some of the questions which were already have been answered here plus i also did some research. but i'm still wondering and dreading, if i have TB. Some of the symptoms that i've read are:
-fever
-dry cough with some production of mucus
-chest pain
-weakness
-loss of appetite
-weight loss
-difficulty breathing
-coughing up blood
-night sweats

i'm a smoker so i'm actually afraid that i might've TB. i've been coughing for a while now (but it's because i feel a phlegm formation in my throat which itches when i smoke) and when i spit i see a small form of mucus, and sometimes due to coughing my back hurts.

does this mean i have TB?

You do have symptoms of TB but also of other maladies. the only way anyone can tell what the problem may be is for you to go to a Doctor. Now rather than later would be wise

You have described most of the symptoms listed in Mosby's Medical , Nursing & Allied Health Dictonary. I'd go to the MD ASAP for chest X-rays if I were you.
