HI. After I have been sitting for a while my legs hurt when I stand. I am 45 but I feel as if I were an unhealthy 90 year old. In fact I feel a lot of muscle fatigue. It is mostly upon standing. I am hunched over and barely walk until I get used to moving and then I am fine.
Hi, you may be having arthritis of the knee joints, or deficiency of essential It D3 and calcium. You will need an X-Ray of both the knee joint, start with calcium supplements and It D3.Revert with an x-ray.
