Confused re diagnosis

OK, deep breath and starting over. After receiving a diagnosis of severe osteoporosis after a dexa and being told that I'd need to start on meds immediately I immediately focused on researching (a LOT) on drugs and various exercise/diet changes. I had a visit early on with the ortho PA who focused on an old spine fracture and spine vulnerability and said that I certainly had spinal osteo.. I didn't go double check the numbers then but remembered after the visit that the hip was the worst. Mostly just wanting to understand the medications (I pretty much do now, pros and cons). This morning, a little bit more familiar with the whole terrain, I went back to clarify the dexa results. They indicate that the osteoporsis is just in my left thigh and femur. It seems from reading more that they infer osteoporosis if there's a fracture. That fracture, I believe, came from a really really hard tumble, slipped on some water and fell backwards, landed hard on ceramic tile just above my coccyx. (Excruciating, ambulance, 8 hr wait on a gurney at Hopkins, diagnosed sprain. But those fractures on't show up on CATS I think.) So maybe not from bone fragility at all. I have multiple other spine issues, previously diagnosed - mild scoliosis, 'bone degeneration', arthritis etc., fairly typical old age problems. Sometimes painful but workable. So the real issue is the hip and femur, which is awfully vulnerable. How might that shift in attention change the way I've been thinking about meds, exercise, movement? I'm inclined to only take meds despite the risk if they'll start me on an anabolic. And the exercises I see seem mostly concerned about spine rather than hip safety. Really exhausted and working hard to manage anxiety trying to systematically wade through all of the stuff. It'd help if I trusted docs more but having worked hospice and heard so many tales involving regret at having chosen to wade through series of debilitating txs it's an issue.Sorry if this is vague and rambling. I'm 74, have always been healthy but never particularly active or athletic, no other major health issues (back pain has been around for decades, and here are the stats: AP Spine(L1, L3, L4) 0.856 -1.8 0.6 Osteopenia
Femoral Neck (Left) 0.337 -4.6 -2.5 Osteoporosis
Total Hip (Left) 0.469 -3.9 -2.1 Osteoporosis
