What is wrong with my body?

Yesterday I started scratching my stomach and noticed that I had mosquito bites on them, as I scratched it appeared that I had 14 or 16 mosquito bites on my body. Later my mom concluded that I had allergies and not mosquito bites. Yesterday the bumps were the same colour as my skin. Today I look at my arm and there are red marks where I scratched yesterday - as if its been bruised. Do I have hives? rashes? My entire body itches and the more that I scratch the more it itches. Even stranger is that it itches in particular sections of my body for example - the right upper arm, but not the left lower arm, the right stomach but not the left stomach the lower left leg but not the upper left leg. What is wrong with me?
