I had chills, fever, no appetite , muscle pain and dry cough one week. didn t take any medication.fever and chills gone after one week,no pain but i still have general fatigue and light dry cough. Do I have a TB? I am so scared. I had TB skin test two years ago and it was positive but chest x ray was normal. doctor asked me to get medication 6 month for prevention, i scared of leaver and nerve damage didn t take medication. i had no other symptoms, but i am very scared of occasional dry cough, although it is not painful. i don t have chest pain but have upper back pain sometimes. i went to X-ray and blood test , it take several days for result. i couldn t sleep keep worrying about my health, please help me explain. thanks and many thanks...
