Hello Geeta,
Welcome to the board. Please take some time to look around my website, starting with my article on this forum (the top post) in the article "How to live better with Hashimoto's Thyroiditis". In this article, there are practical ways to find out if there are culprits in your lifestyle causing symptoms that might be able to be controlled. After that, check out my main website ("home" button on this forum) and maybe there will be further tips to help you there.
Because of the individual natural of this disease (meaning all of us tend to have a different set of symptoms), we kind of need to "play detective" based on many aspects of our lifestyles. My article helps you sift out some of the main culprits that could be lurking behind your symptoms.
Hope this helped.
Take care,

Mo
