Hi as I have said, I am going through a bad patch with my knees swelling up. I have had a injection in the right but the left is just has bad. I used to walk with one stick for a short distance and could even get up stairs. Now I am having trouble just walking with two sticks. I spent last night downstairs in my chair to give my bones a rest. They say you should excersise, which I try to do but when your in pain how can you. If you sit to long it hurts when you get up, if you walk and excersise it hurts and can damage your joints. Anyway I am thinking of getting some crunches when I'm this bad, does any one find it better then sticks.
