Physical exam: Rather than look to tie symptoms together, you should get a physical exam from an orthopaedic surgeon. You may have spinal disease compressing nerves that supply the sensation to those areas I.e. Sciatic, obturator, sural nerves. However , a careful medical and surgical history, range of motion and physical exam and imaging will provide definitive answers to your questions. Good luck.
