Hi, My name is Ted. I am new to this site. I have arthritis in my right knee, left foot, and starting in my right foot. I do have some numbness in my toes and progress to the heel later in the day. I went to see a neurologist. He did an EMG test, nerve conduction test, MRI on my lower back. All tests were fairly normal. Did complete blood work, including testing for autoimmune disease. Only thing I was low on zinc. Doesn't want to do a small nerve biopsy, because it could cause permanent nerve damage. My biggest problem is the lack of energy in my legs. My upper body feels goods.
