Hi wellcome to H.C.M.Forum. it appears to be recurance of the old infection & excerbation of the symptoms.
as you are exposed to allergens, or stoping the drugs without completing the course.or may be another infection. it is probably uvulitis, or breathlessness due to bronchial congestion.
i advise you to consult a chest physician for diagnosis. you may have to get the tests done like, TC, DC, ESR
, AEC,SPUTUM FOR AFB.IGM FOR TB etc.
besides i advise you to stop taking fruits, cool water, cooldrinks, icecream etc.for few days.don't worry you will be fine.
