@steveinarizona I don't play golf, but my physical therapist indicated that the twisting during the golf shot has caused back problems for her patients. (Tiger Woods has had spine problems.) It seems one thing affects something else. If my pelvis shifts out of good alignment (from SI joint movement), it causes back pain on one side for me. I could see how a golf swing may add more to that if pelvis alignment is off. The misaligned pelvis also affects the knees, and I know if I get pain on the inside of my knee, that my pelvis has shifted a bit. I work to keep proper alignment by leveling my pelvis with some stretches and have orthotics in my shoes and according to my physical therapists, that helps prevent uneven wear and tear on joints. It's kind of like that old song, the hip bone's connected to the leg bone.....

As you said, one problem can conceal another. That hand surgeon who did my carpal tunnel surgery was not a good person. He had made a mistake in his records about which side was affected and refused to correct it saying medical records can't be changed. He even hid from me when I was at his front desk and had his staff tell me he was not there, but I had already seen him. I had to make an appointment to get him to speak to me after I came back with a diagnosis from another doctor that I had thoracic outlet syndrome. I asked him to send me to physical therapy and he refused. His excuse was he would not know if the PT was helping me or not and would not be able to judge if it was successful. Apparently, he did not like being called out for a medical mistake of a missed diagnosis. The surgery was fine. I showed him my hand that was blotchy purple with concerns about the circulation because it was cold and he took my pulse and told me I was fine.
