I haven't seen the inside of a gym since last Wednesday.
Thursday I was so sore from Wednesday I took a rest day to let my body heal. Friday, My knee started aching. At first I thought I could just deal with it, but by the time I arrived at the gym, after walking up and down the subway stairs, I realized that running was out of the question. So we walked from Wall street(ish) up to Canal Street. Saturday, the pain in my knee was so bad that I could barely hobble around the apartment. It hasn't felt that bad in years.
Sunday, after three days of no exercise, I forced myself to run through a pilates video that I knew was mostly floor work, and therefore easy on my knee.
Today my knee feels to be at around 80%. There's a small twinge in there, but nothing serious. I'm going to try the gym today, on a "see as we go" basis. I'll start out on the treadmills, but if it starts bothering me, I'll have to switch to something less high impact.
It's a setback, but it's small. I'm frustrated that my knee is still acting up this badly this long after the surgery, but I'll deal. At least I can walk, and usually, run.
