I have a persistent cough but it only happens when I felt hot. sometimes it also occurs during sleeping. I've had this about more than a month. I have no loss of my appetite and no loss weight too. I can eat a lot. But this cough really keep me in confuse because for sometime, i cough for the whole day. I've done the x-ray but nothing interesting in there. Have also a lot of kind of medicine

Symptoms are:
1. Cough that is worse in the morning hours; hemoptysis (blood in the sputum) can accompany cough
2. Mild fever, headace, chills, night sweats
3. Chest pain from pleurisy
4. Breathlessness
5. Swollen glands
6. Feeling unwell, fatigue
7. Signs of pnemonia

I think you dont have tuberculosis, maybe just an allergy on air thats why you cough when exposed to it. if you already consulted a doctor and still not getting well after taking his medicine prescription, then its time to change your doctor

Cough deep. Get sputum examined for Acid fast bacteria. that confirms T.B. Evening rise of temperature, dry cough,and loss of weight are other symptoms.

Please see the webpages for more details on Tuberculosis. Please consult a chest physician for second medical opinion.

It could be heat induced asthma.
