Keep Getting What Looks Like Mosquito Bites In Different Areas

keep getting what looks like mosquito bites in different areas of my body..the latest area is my wrist..looks like ive been bitten by a mosquito about 10 times on my wrist & it is swollen....this just popped up & started itching out of no where last evening.I dont think it is mosquitos because i havent seen any yet this year..what could it possibly be?
