There have been small mosquito like bites all over my back , some on my bums, thighs and upper arm. They look like some insect bite and they itch every morning. I thought they are bed bugs for which I sprayed the bug spray on my bed. Put out the matress in the sun twice. But after few days the itching comes back. Specially when I get up in the morning. After bathing and even while and after sweating. Since I'm a dancer I sweat a lot. I dont know what to do. There are so many bite marks now and are increasing everyday , they look like some kind of infection . Pls help.
