I got bite by a mosquito this weekend while i was camping. my mosquito bites always swell up.?

but now i am more concerned with the swelling because its painful i got huge welts i've always been like that but this time i think there might be something wrong. they're huge and bright red and really hurt. i put hydrocortisine and calamine lotion on but that only took the itch away. i also took benedryl but that did nothing so does anyone have any advice? does anyone think i should go see a doctor?
