Yep, you will be surprise but the medical field, and sciense in general, doesnt work the way our intuition works, alot of times problems that seems really hard and complex to us, get solutions much faster and easier then problems that seem simpler.
A heart can be transplanted, yet a problem for example chronic noises in the ears has no solution. My mom suffers from it for years now, and I heard that it happen to alot of people in certain age (~50), and all the doctors has to say is "you just need to live with it..."
I have a chronic problem that looks like IBS and it really effect my life and several aspects, and yet with tons of examinations and private doctors I have been to, no one has any idea even what this is, not even talking about treatment for it, they just say "well you just need to live with it...", and this is actually what the doctors will say to most of the health problems that you will encounter.
