Suggest Treatment For Nose Congestion And Itching Sensation In The Eye

Hi I seem to be having an allergic type reaction whenever I m in certain rooms of my house. Especially in my bed room. I wake up each morning with a blocked nose and sneezing, eye itching and irritation. I feel like I have the flu. It s starting to wake me up through out the night now. I ve dusted my room, cleaned my bed linen, swept my wood floors, even moved flowers out and nothing has changed. Do you have any idea what could be doing this? It s making me miserable and I can t sleep
