7 months after my left knee replacement and 4 months after my right knee. still in pain when walking! i would love to hear from anyone that can tell me when i will be able to walk for more than 15 minutes without the pain becoming unbearable... i go to the gym now which does help when im doing the excercises, however, later my knees stiffen and cannot walk at all! so back to bed i go. should i be back to normal now? just want to start my normal life like going for a walk in the nice weather without terrible pain..... couldnt get round b@q last week without nearly bursting into tears!
