[|Human|] I have pain behind my knees which travels down into  my feet, particularly after standing for long periods of time. Also when i get up in the morning. However, pain seems to subside when i walk around for a while. Certain bending positions at times seem to agrevate the problem. Can you help. Thanks.RegardsColleen
[|AI|]  Hi, There are two possibilities If you have a history of fall or repeated back movements or low back pain then there is a radiating pain from a pinched nerve in lower back, most probably L4-L5 and L5-S1. And if there is a swelling, warmth or tenderness on the back of your knee then there is a bursitis in the popliteal fossa (back of your knee), compressing the nerve, hence the pain. For low back pain you can have hot packed, back exercise (avoid bending movements) and Physiotherapy will help you. However, an x-ray is advised for the verification. In case of bursitis, apply cold packs, and an examination needs to be done to know the cause. You need to take rest. Walking and mild knee exercises will be beneficial in both the cases. Hope this solves your problem. Let me know if I can assist you further.
