Hello
You are having DRY cough since 3 weeks .
Now from last 3 days you are having , fever ( light 0 , head ache, body ache & red spots
These all symptoms may be due to these reasons , these includes .
1 Asthmatic allergic
bronchitis , diagnosis can be confirmed by physical examination by a doctor . Usually there develops whistling sound during breathing due to allergy . Allergy causes
bronchoconstriction and hence dry cough .
When such patients visit in my clinic I advise them to take monteelukast+ bambuterol tablet twice in day . I also advise them to take dextromethorphan+
chlorpheniramine maleat syrup twice in day.
2 The next reason of such symptoms may be
tuberculosis ( history of illness of last three days ) . Diagnosis can be confirmed by X ray chest and blood examination for C B C & E SR.
3
Typhoid fever may be the next reason with allergy . Get in blood for W idal and serology test.
In my opinion you are having allergy with super added infection so consult a physician get his opinion.
Good luck.
