Hi, I want to enquire if you think I need to go see a docter or will Brufen work...From Tuesday I have suddenly not be able to walk in the back part kf my left foot, then I have a sharp almost sprain like pain down the left side of my foot(almost under die ankle knuckle ) if I sit for a while its fine, but as soon as I start walking it hurts, but there is no pain when sitting. I walked on my toes so far, but now even that gets painful when walking, now I try to walk on the inside of my foot to prevent it from hurting. Do you have any suggestions
