Getting the right fit is an iterative process. I had problems mostly with my hands and wrists. I got a pro fit and it helped immensely, especially with saddle selection and position. I tweaked the fit a bit, mostly bar height and reach. It's not perfect, I still get some numbness in my hands, however I can go 50 miles without too much discomfort in the hands. Much farther than I could before the fit. Being 67 years old I expect to have some pain, hell, I get pain doing nothing sometimes! Pre-medicating yourself with ibuprofen helps.
