Do I be more grateful and keep my mouth shut?

My boyfriend has been interested in learning about me and my health. I appreciate him wanting to learn about everything, but when it comes to him he does research on my health problem and tries to find “cures” or treatments. It frustrates me because it makes me feel like he’s saying you don’t understand what is wrong with you so you should try this, this and this as treatment… it almost makes me feel like he’s saying thinks I never tried to find ways to treat myself or find doctors who are capable to treat my issues.
