Some are, some aren’t. The obsession, worry and hyperfocus with any symptom is. Meaning that you can have say cataracts, which can change your lifestyle but if it becomes such a burden of suffering, then there is most likely TMS at play.
I believe cataracts, the hypertrophy, and hearing loss and most likely heart valve issues are not TmS - although the valve problems could be exasperated by stress, it’s more commonly a lifestyle illness that usually presents with aging and can be occasionally congenital. There are various forms of arthritis, common with aging and I see osteoarthritis commonly in friends with TMS. I myself was diagnosed with it showing up in imaging and 5 years later magically disappearing in that area. I have a finger that likes to get cranky every once and awhile but it doesn’t loom large in my life.
I think it’s important to ask yourself how you are doing emotionally with aging. What might better support you where you are at emotionally with it eg. Are you surrounded by people and things that make your life satisfactory? What would you change if you could? Do you have an internal feeling of safety, of balance, and externally are your needs met? If so, you might look at where there is stress that you sometimes don’t acknowledge?
Lastly, you might ask why you find a need to separate what is “medical” from what is TMS? Both have mind and body components and both benefit from doing the emotional work, both usually have a fear basis.
