im thinking that you have the flu or sometimes when the weather changes that can happend also, i would suggest medicine, soup, fluids, and hot baths its good to just let the hot water hit your chest to open your pores then vapor rub, works every time
it seems you are having upper respiratory tract infection early , probably extending to acute bronchitis. symptoms are not enough to come to a exact diagnosis. you better take Amoxycillin 500mg tds, Deriphyllin 150mg bid, Salbutamol 1mg bid
Does you face hurt checks, forehead, inbetween your eyes? Do you have a headache? Your symptoms sound like a sinus infection. If so, you will need an antibiotic. See your doctor.
