Absolute exhaustion set in suddenly last evening. Had no energy at all. So tired, l was in bed by 8pm. Had to ice the knee 3 times during the night as it was quite sore and achy. Not doing too many exercises yet as want to give it a chance to settle down a little. Got an awful lot of bruising which is causing dull aches and tenderness. I'm taking my pain meds regularly and elevating when downstairs. From reading the journal l kept last time, this is pretty much normal, amazing how easy you forget the pain and discomfort associated with this op.
