From last 2-3 months i am noticing, i feel tired always. In spite of proper food and sleep. Month back I fall ill, and doctor told me that my immune system is very weak but that time I was on medicine of fever. So, he told me to come again for immune problem. And Second problem which I face a lot when I do running, skipping or any such type of sport  then bone of my leg start paning and when I walk fast then pain starts in my ankle. So, now I am confused I should go for full body checkup it should consult normal physician. Please suggest.
