I Have Loud Signal Noises In My Head All The

I have loud signal noises in my head all the time, it seems to get louder when around chemicals, but not always just then. I cannot stand heat at all, my face gets red and I pour with sweat even in air conditioner places, especially after my morning shower. I get severe vertigo if exposed to perfumes or cleaning chemicals, tide, pine Sol, gain,etc. It's driving me crazy and I am on anxiety meds. What can this be?
