My knees the last few weeks have been bothering me (no change in amount of time working out, type etc) -- so I can't see how its connected to that.
About a year ago, I noticed that "lovely' crunching noise that I sometimes heard when bending my left knee. But had no pain. Now sometimes my knees are making themelves known when walking up and down stairs etc. To be honest, not happy at all about this. Between my knees and my feet, grrrr.
I thought the twinges in my left knee the last couple of months might have been caused my foot surgery back in September --- perhaps overcompensating, gait getting messed up by walking with the boot cast for a month plus. But I'm having issues with both knees, but mostly the left. And, its been worse the last few weeks, and its been months since my foot surgery/wearing the boot etc.
I'll be calling my doc to check it out but in the meantime which exercise machine might be the best to work out. My tiny gym in my bldg has a treadmill, rower, ellipical, bike, and a Healthrider looking thing. Or would just walking outside be best? I'm thinking the elliptical has the least impact. Or maybe it doesn't matter (assuming when I'm working out there isn't any pain).
