I'm tall too, and to be honest, us tall people suffer pain everywhere since the world is not designed for us. That said, it sounds like you need more physical therapy not saddle work. If the saddle won't fit you, you have to adapt to tolerate the saddle -- the same as we do for everything else.
Since you mentioned your age how's your test level? Low test levels can accelerate muscle and bone degeneration, so if its outside the normal range you may want to investigate treatment. You also didn't mention your weight/physical condition, so if you're over fat that will certainly add to you physical discomfort.
