He has severe back pain and his family has slip disc history. Can the back pain be because of slip disc? He was under severe stress for 3 days and had a jerk in the back while playing. What are the chances that he has slip disc pain? He has no pain in any other specific region like arms or legs or neck.

My sister's himoglobin is only 7.20.she was suffering from body pain.what should she do?

Whenever I walk quickly the muscle above my ankle region on my left leg swells temporarily. I feel a burning sensation and mild pain if I continue to walk. Then I have to stop and wait till it's gets over which is usually around 5 to 10 minutes. Recently I have joined gym and whenever I walk on treadmill it happens again. But when I run it doesn't happen.

I am feeling pain in back of neck to left shoulder alongwith little pain in left hand as well with the movement of my neck. It might have started since last week's workout in gym.
