Welcome to healthcare Magic!
You are suffering an insect bite no doubt about that.
You are getting bitten everyday then why do not you treat your house with insecticides yourself.
These days the insecticides come in sprays and are quite handy and cheap.
Get a canister of Pyrethrum based spray and leave the room closed for 6hours after spray and get rid of all insects.
Time being you should take an anti-allergic like Benadryl
25mg thrice a day for three days.
The problem would subside by itself.
Wish you a great health!
