Peggy, I thought about it because you mentioned you felt worse after eating biryani - does it have a lot of spices?
Going gluten free helped me somewhat, but I knew that there had to be something else because I still had issues with rosacea and tinnitus. I've also had vertigo a few times. A rosacea site led me to the salicylate issue and my rosacea is much diminished now. My tinnitus is directly correlated with salicylates, I have found. It may be something to look into.
I hope you find a solution.
