Am i allergic to insect bites?

everytime i get bitten by an insect (black fly, mosquitos, ticks (only once when i was camping) ) the bite swells up to the point that its hard and i hardly scratch them when i realize its a bug bite. some are ok and just go away but other seem to stay swelled for a while and really hurt. i once got 14 black fly bites when i was at my aunts house for a bonfire and i was so swelled up i had to stay home from school the next 2 days. when i got my tick bite when i was camping last summer it was HUGE and it hurt so bad i couldnt even touch it and it was swelled up about a cm off my arm! this also happens with spider bites and any other bites youre able to et in the summer.
