I was stung by a bee last sunday and went into anaphalactic shock. Profound drop in blood pressure, wheezing and starved for air. 3rd time in 15 years. Gave myself 0.3 epipen x 2 and a mouthful of children elixor Benadryl. Paramedics gave me due-neb aerosole breathing tx. after 10 horrible minutes I began to get better. was wondering if there are any otc breathing tx I could keep handy that would better lessen the tight airways.
