I’m having frequent asthma attacks,25 male with around 55kg

Patient: I’m having frequent asthma attacks,25 male with around 55kg 5’7” height,it started slowly around when i was 15 years old back ,then it was very mild and occurs once in a few months mostly due to my dust allergies,im allergic to dust in general and dust mites,cockroach’s . no food allergies found till date.now the asthma is getting stronger,im using an inhaler almost daily,its an asthalin.ive also gets head aches ,blocked nose when in A/C rooms,blocked nose in almost all mornings,followed by sneezing.if dust allergies occur they start with itches in eye or nose frontol,then sneezing ,then it may either improve it to cold or headache or both .now im in a situation where i cant even sprint a 100m,used to do way more than that.ive seen many doctors most of them suggest some antibiotics,like deryphilin etc.they stop the symptoms and asthma for a week or so but they come back as usual.for year now i have not taken any medication for asthma just using inhaler.is there anyway to reduce/stop this improve my health .
