Hi Dear ,
Welcome to the board of Health Care Magic,
It seems to be you are allergic to some agent present in the garden probably pollen grains or dust.Better you avoid the exposure further.
Plse get treatment for your wheeze ,sneezing
and fever. by taking some antiallergic medicines. Nebulization with some bronchodilator
medicines. if wheeze do not respond to nebu. then go for the some steroid
nebulization. because there is fever you have to think of some antipyretic
or some times antibiotics also as your sputum is becoming green coloured.
Hope your query is answered.
