As a child I was in good health. When was 13 years old I lost weight and became weak When I was 19 I had a few grey hair. I was very thin. Now I am 62 years and am getting weaker and weaker I have no energy at all. I cannot go out everyday or do much housework I get tired and exhausted. I have to lie and rest I feel hungry. I feel dizziness its worse in the mornings. I have done several tests. Dr. Says my tests are normal. I am lacking Vitamin D my bones are weak my nerves are sensitive. I have gained weight now For the past 5 years I have heel pain I used to walk a lot .I have lot of pain on both feet and my toes are swollen and sometimes numb is there any cure .for weakness. I am taking medicines for cholesterol blood pressure and calcium tablet. One Dr. Had asked me if I had done a profile a full body scan I have not done this test. Do I need to do this test.
