bites everywhere? what is it?

I can’t understand what is wrong with me. I have bites on my 2 feet, on my thighs, side of stomach, right hand, near my navel, my back. They are very itchy, i can’t help scratching them. I tried to squeeze them because the bites in my feet look abit swollen and whn i did, abit of liquid came out. No not blood. Abit of blood only when i scratch bery hardnd often. I dont know of this is allergy, insect bites or what i tried vitamin a ointment, antiseptic cream and cetomacrogol cream. Help pls
