[|AI|]  Hi. The numbness and blue discoloration could both be due to be arterial insufficiency since they detected sluggish flow in the popliteal artery behind the knee. With a high cholesterol you may have plaques in the arteries, and you need to work on bringing that down. Exercise is advised to help improve the pumping action of the muscles to improve blood flow. The bulging discs in the lumbar area can cause backache and pain radiating down your legs. I suggest get physio and good back care and strengthening exercises.
