Can i join the army british?

i am 15 and am joining the amy next year (AFC) and 2 years ago i was given an inhaler not for asthma but for shortness of breath and that wasn't that bad when i got my inhaler i didn't even take and i am fine but on my medical records it will say i was given an inhaler and i know you have to wait 4 years without one till you get in the army but if i go to my GP and get them to check that i am ok will the army say yes
