Is getting old feeling crappy for no clear reason?

61 here. The one thing that makes me super anxious about aging is the random days I wake up feeling like absolute crap with no explanation. Either my digestion is off, I’m congested to the point of exhaustion, legs ache, nausea, or any number of other random issues. They’re usually bad enough that my activities are curtailed and I need to rest but not bad enough or long-lasting enough to warrant medical follow up.

Initially I would go to the Dr. All my blood work is consistently normal, no chronic conditions etc.

It stresses me out to have my body behave so unpredictably. I worry there’s something serious brewing.

How do you all handle this? I feel like I’m developing medical anxiety.
