Re: Numbness in leg and swelling in foot???
There are many possible causes for the condition you're describing, from nerve impingement, to shin splints, varicose veins, or Phlebitis. Does anything you do - other than taking the weight off the leg - seem to make it better or worse? Is there heat in the region? Some of the problem may actually come from the lower lumbar spinal area, hips & the sacral region as there are nerves which exit from those areas that run down into the legs. You may want to see someone who deals with muscular/skeletal conditions such as an Osteopath or Chiropractor as they may be able to evaluate the overall contributing factors that could be related to the symptoms.
Good luck & let us know how you're doing.
