I had my total knee replacement surgery August 30, 2012 and thought that I would be as good as new, hahahahaha!!! I have been in such severe pain that at times it is so unbearable I want to scream! I have severe aching pain with many sharp and stabbing pains throughout the day and night that wake me up in tears also. I thought that I would have way better range of motion, not! When I straighten my leg it locks on me just like it did before the surgery, why? My knee continues to have a fever, I ice it throughout the day to keep the swelling down, its funny though that my knee feels like a 20lb ball but to look at it it doesn't look like it. I do not, DO NOT feel that I have any stability in my knee at all, I am very fearful of falling all the time. When walking for any period of time like grocery shopping or walking the dogs is a very hard task but I try to do it because they say how good walking is for you, but in turn it is so very painful is there a benefit? For about the last month I have been experiencing a severe burning feeling up the back of my leg to my hip and down my leg to my ankle, I am so beside myself as to what to do. My Dr. told me that all I need is physical therapy, I do that and it just hurts but I keep doing it, no pain no gain, what ever! Why is it that the Drs try to get you off pain meds when that is the only thing that keeps me sain, I do not think one of any of these Drs has ever had severe knee pain because they would certainly not be doing that to their patients! If anyone has any answers to my questions or can put me in the right direction please, please let me know!
