Feet numbness and difficultly waking
I am a 48 year old male and was physically active until now. A couple of years ago I started having difficulty in passing urine and eventually after a long list of test, I was diagnosed with the Urine Retention. In addition to this my bowel movements are now every 2 or 3 days. I started self cathetarization which is relieving but recently I started having difficulty with walking. Both feet has burning and tingling sensation and it is stressful to walk even a short distance.The MRI's do not show any major disk degeneration or tumors in my spine.
There is continuous burning sensation in my lower back and shin muscles all the way to the big toes. Any suggestion as to what could be causing this would be appreciated.
