<s>[INST] My son had a bad asthma attack last night and was really struggling to breathe so Much that I thought I was gonna lose him. As he taking inhaler my legs started to go from Under me and I couldn t breathe, I started to feel faint. My husband helped my son as I swayed into the bedroom and collapsed on the floor . I tried to breathe deep and slowly and started to feel Better. Felt so dizzy . I was okay and my son had calmed and was better. When I a woke the next morning I had a bad migraine and led on the floor as I felt dizzy . This went after A while. We later took My son to a&e and I was shaking, again dizzy . I m concerned what happened? I ve fainted when I was very young but is it just down to the stress of the situation? [/INST] hi, this is called syncope attack..in this person has black out..everything starts appearing dark nad you feel light headed.. it usually happens due to sudden stress as you mentioned about your child having asthma attack.. if this happens often or without any stress you should visit your doctor for further assessment.. also get your hemoglobin checked.. because syncope attacks are more in anemic patients thank you dr.mukesh </s>
